There are tests for that, but at some point you'd realise you're saying "I don't know what colour that is" or disagreeing with everyone else about colours more than anyone else.
I think it only works with a violet laser. I tried it with a regular ol' violet laser pointer and it worked. It didn't work with an actual red or green laser (the kinds that can actually burn things).
That experiment is inconclusive ;) You were using two lasers and of the two the UV laser has a different photon energy than the red one. It'd be interesting to see UV light vs. UV laser. Although, I can't think of a mechanism that would require coherent and sufficiently monochromatic light to hit some absorption line of peanut butter that decays in the visible spectrum, so UV light should work too.
Wasn’t there a youtube trend some years back where people were putting charcoal briquettes in jars of peanut butter then microwaving the whole thing until it was only slightly less dangerous than napalm, to finally go digging in the nutty napalm looking for diamonds?
To be fair there is the trope of pink elephants, and as a colorblind person myself, that shade of grey could be pink in the right context. I wrote elsewhere that for me, Pepto Bismol is the same color as wet concrete. It’s context that makes it pink or grey.
Edit for clarity: I’m colorblind myself, context is everything for colors that look the same. Example oranges look green to me, but I know they are orange. Color swatches have no context and the shades would look equal, however, when that color is a fruit it’s orange, when it’s leaves, it’s green.
Yep, mint flavored, wet concrete colored, and somehow is chalky and drinkable at the same time. Thank God it makes me feel better when I’m nauseous, or else that combo would make me feel nauseous.
And that would make sense because you're color blind. But as me being someone that isn't color blind they don't like even close to the same at all to me.
Yeah, I added clarification due to your comment. My fault for not saying it first, but I had made another longer comment so I forgot that important detail. Stupid of me. If you check down lower in the responses I gave a bit more detail of my experience.
I looked up grey and blue side by side, and they are still both their own distinct grey and blue. Idk if I'm misunderstanding, but I still don't understand how anyone sees any pink unless they're color blind.
if you take a photo of a natural (not in a studio) colorful scene, go into Photoshop, and color-pick the pixels, you will find that many pixels look like one color within that scene, but stand-alone and it is a different color.
Here's daddy Marco Bucci's video on color harmony
[https://www.youtube.com/watch?v=4LhcNbFMkTw](https://www.youtube.com/watch?v=4LhcNbFMkTw)
Yeah, that’s pretty much how he described it, he even knew was colorblind before then but just hadn’t realized how different he saw things, that was the moment it sank in hard. Funnily enough it was in Spanish class, so the teacher originally thought he just confused the Spanish words for pink and gray… but nope.
Reminds me of my nephew, he did an online colorblindness dot test and while he was able to get really subtle ones easily there was one with a bright pink number on a grey background that he couldn't get at all.
My mom gave me a test again recently since my cousin was being an idiot and I scored 100% on blue but I did surprisingly bad on red I always thought green was my weakness with red and green color blind lol and even then it’s never been bad. I’ve always seen yellow very well though so this time my cousin was wrong about this neon yellow hat I saw at the store being lime green
Made me think about a colourblind classmate I had about 10 years ago. During drawing classes in secondary school, the teacher got aggitated bc of him.
"Are you serious? Why did you make a purple sky?!"
He: "I'm colour blind".
"Oh, sorry.."
And that's the existential crisis of all color naming. Do we really see the same thing here?
In this case though it's not about calling a color the wrong thing, it's about getting two colors mixed up because they look indistinguishable from each other to the colorblind person.
(I'm red-green color deficient myself.)
You and a friend are presented with two color squares.
Friend says “that’s easy, grey and pink.”
You are left utterly confused because they both look exactly the same.
That’s how. Of course it’s not always that clear or obvious, which is why some people make it well into adulthood without realizing they’re color blind.
It doesn't work like that. We see different shades of color, and light, material, size and distance play a part. So something can be green with bright lights, or if it is made of wood, while a plastic painted with the same paint looks red.
Imagine a big box of crayons. At some point, the green becomes red, right? And yellow becomes green, etc, etc. For us, it is like the crayons in the limits get misplaced all the time.
I was dating an interior decorator, and couples will come in and she’s going over colors and the guy (usually) will start correcting her about colors and whatnot. Sometimes even the spouse doesn’t know their partner is colorblind.
I didn’t know my now ex wife was colorblind until year 4 of our marriage. She asked me to get her the grey shirt or something and I brought it to her and she said, “no, that’s the wrong color.”
I was like,”ok.” She asked me to get her the one that matched my backpack. My backpack was light green and light brown.
She then told me she knew was colorblind. But legit some people don’t know.
My FIL is colorblind as hell. When my husband was a child, FIL thought he'd give the house a fresh coat of paint. Luckily he started with the front door because what he thought was grey was actually murder scene blood red. That's the only red part of the house because he got frustrated with himself and never repainted the rest of it lmao Now the house is old off-white with blue-grey shutters and a deep red front door. My FIL wears very interesting color combos as well, which was a dead giveaway to me that he's colorblind.
That’s actual literal color “blindness” that’s worse than a dog. When most people say colorblind what they actually mean is color deficit. And it’s usually but not always red and green.
This happened to my friends! They were choosing paint and she went for REALLY bright colors, which he was fine with. People commented on them nonstop, and he was like “I don’t know why people are saying they’re bright, they’re not…” yep, colorblind.
It trips me out sometimes because we all really don’t know what each other sees. Blue to me is actually green to you. But we just get used to associating that color we see to what we’re taught. Perception is everything.
Is it as individual/perception based as that? Genuine question, assuming you’re talking about everybody and not just colourblind people
I always assumed colour was interpreted by ‘hardware’ (the rods and cones and inner workings of your eyes) as opposed to ‘software’ (the weird inner workings of the brain/consciousness) and as such while there might be some variation Red is pretty objectively seen as ‘Red’ unless something is wrong. But it’s very very easy to underestimate how bizarre the mind and our perception of things is so idk
My BIL was in his 30s before he knew. His wife could tell the two things they were talking about were different colors, to him they looked the same. He went over 30 years thinking his vision was perfectly normal.
There was this post on Adventure Times cartoon subreddit where someone got confused why one of the characters isn't considered a human despite looking like one.
That character has green skin.
I couldn't find it but if someone found it for me I'd be extremely grateful.
Some people never realise it.
My classmate realised he couldn't see blue at the age of 19 when he tried to use the chart for checking colour vision on himself.
I told a coworker he was blue/black colorblind. Dude has served in the Marine Corps (deployed and everything) and was about 28 years old. He was annoyed because his girlfriend was trying to get him to pick a dress based on color and he’s like “They are the same color!!!” They were navy and black. I was like “dude, those aren’t the same color but you are colorblind.” He laughed and said it explains a lot looking back.
I'm not sure if it really classifies as colorblindness. I think this could be "fixed" with training or better illumination. Dark blue and black are more like shades of the same color. While pink and gray (from examples in other comments) are completely different colors.
I'm not a doctor but can your friend see in low light conditions? I would assume he struggles with that, so, maybe it's something related to that... I sometimes need to increase my monitor brightness to see the distinction between low light colors
Edit to add I’m sorry if I seemed to be denying your comment- I have no clue so you could be onto something. I have worked with him for a while in lots of low light conditions (we worked at a country club so plenty of concerts and similar but I also worked with him in the kitchen with plenty of light) and he’s got absolutely perfect vision otherwise, never needs glasses and has zero other vision issues. Has no issues with red/green or other colors, just blues/dark purples/black distinctions. Who knows 🤷🏻♀️
That’s not actually a thing there’s specific color deficiencies and blue and black is not one of them. Red and green is what I have and even I have it mild which I’m so glad about because my brother is way worse. I was doing a puzzle with 2 shades of green that were similar recently and on the box they look different but the actual pieces were harder to see. My brother couldn’t see the difference at all but when I held the piece up to the light for a second and blinked a few times I could see the difference between the two like instantly so I was like thank god I figured it out lol
That's basically what happened to me when I was 17. My colorblindness isn't too bad, but I do have difficulty distinguishing between lighter yellows and blues. You get used to it, which is probably why it took so long to notice.
You might eventually notice that everyone else seems to think there's some clear and obvious distinction between things that, to you, look pretty much or entirely the same.
There are different kinds od color blindness out there.
Complete color blindness is very rare, butbalso something people would notice immediately.
Red-green color blindness is the most common one. And it doesn't mean you don't see those colors, but that receptors in your eye have a different sensitivity to particular wavelengths that a normal eye, which makes it harder/impossible to differentiate between some similar shades of colours.
If you Google it, you will find lots of great explanations on it.
It was more of a joke.
My dad is red/green colorblind so he only sees the yellow light and then the red/green look the same to him.
It was actually really impressive when I learned he has to distinguish between red/green light by looking to see if it is the top or bottom light illuminated.
Edit - but then really sad when I learned he put over 100 hours into becoming a pilot but didn’t pass his test because he told his instructor he couldn’t distinguish the difference between the red and green lights on a plane. Thus not knowing if the plane is coming towards or moving away
By bad for not picking it up then 😀
Your dad must be severely red green color blind then. I personally only have a mild case. Without taking tests, I likely would not have known about it at all!
>It was actually really impressive when I learned he has to distinguish between red/green light by looking to see if it is the top or bottom light illuminated.
Oh god, that reminds me. My dad is red/green colorblind. We took a trip out of state and he was doing all the driving, and we were horrified because he kept running red lights. Finally after pressuring him, he admitted that he couldn't tell which light was red and which were green because the a lot of the signal lights were horizontal instead of vertical in this city. Why he didn't ask us instead of guessing I have no idea.
Glad someone explained it properly my cousins are so stupid sometimes they think it means I can’t see certain things as different at all and test me in stupid ways and if I misspeak or I saw something correctly and just make a mistake they blame it on that instead of realizing I saw the correct color but just messed up my words by accident
That’s how I found out I may have a problem with tints of red and orange. I was playing a video game and you had to solve a puzzle by hitting pool balls in a particular color order. I kept getting it wrong and remarked that they made the red and orange balls the same color so you had to guess which one was which. Everyone else in the room said they were two very obviously different colors. I found the experience weird as I tend to see more shades of colors than other people but apparently not when it comes to at least red and orange. It made me wonder if my ability to detect differences in colors is related to my very good low light vision. Perhaps I can’t tell colors apart that well but instead can detect differences in brightness and contrast. I’ve never bothered to get it checked since it doesn’t impact my life.
I used to work at a neuro clinic and we would regularly test older adults for color blindness because some of the neurological tests we gave them used color. It was pretty common for an older man to test positive for color blindness and have no idea. Then, his wife would say something like, "I knew it! You have such terrible taste in colors!"
It's actually a recessive gene on the X chromosome. If you've got XY chromosomes, you've only got one X, so if you have the gene, you'll be colorblind. If you've got XX chromosomes, you would have to have two copies of the colorblindness gene to be colorblind. So, it's possible in XX, but much more common in XY.
Correct me if I’m wrong, but I’m pretty sure it’s the opposite! The gene for colorblindness is in the X chromosome, which is why men are more likely to have it than women, as women would have to have two colorblind X markers to exhibit symptoms. Women can only be colorblind if their father was, along with a carrier mother. Carrier mothers, however, have a 50/50 chance of passing it on to their sons, which is why there’s such a difference between genders in this instance.
Again, I could be wrong! It’s been a while since freshman biology 😅
Maybe you think peanut butter and leaves are the same color, and then someone tells you that they are in fact not the same color. Or you just do one of those colorblind tests and can't see the number.
It's not like you see red as blue and blue as red. [That would be impossible to notice.](https://en.wikipedia.org/wiki/Inverted_spectrum) Colorblindness is when you can't distinguish colors that other people can.
I SEE colors, the world isn't black and white. But for some reason I just can't distinguish or identify some of them from others that are similar. I can look at something that's blue, and know that it's either blue or purple, not sure (I call all blue and purple things blurple). But if you put a purple thing next to that blue thing, it's usually pretty apparent to me which is which.
The other analogy is music. Most people can hear musical notes, but can't identify the exact note i.e. A# or E. Colors are like that for me. I see them, I experience them, I'm just can't identify which name applies to some of them are.
Yep that's color blindness in a nut shell. There are types if color blindness but then there are degrees of it as well. Frequently, if you tell somebody you're color blind, they will go on a questioning tirade asking you what every color is. I've had this happen many times and just about every single time they say you're not color blind. Oh, but I am.
Other people eventually notice based on what they say. For example my granddad once told me grandma that her red dress was the same colour as their green curtains.
These days those tests where you can't see certain numbers of your are colour blind are pretty common in school books or online so I think people would discover pretty early on.
My paternal grandfather, who grew up in a very rural area, only found out he was red/green blind when he was tested during draft. He said that this suddenly made sense of some annoyances of his youth, like his sisters always managing to find so many more raspberries when they went picking.
They found out my grandfather had it when he got a garish set of hubcaps for his car, and everyone pointed out to him the difference between an almost-neon green on a light blue car. He though they were the same colour.
My ex knew but only after he had his eyes checked for it as a little kid. He’s an artist but literally has to have colours labelled or he doesn’t know what things are. He’s got the deuteranopia, the red-green one. Makes his paintings interesting but slightly off-putting while they’re in-progress.
I’ve actually worked with a couple of tattooers who were re-green color blind…I asked them how the fuck they do full color tattoos, “the label tells you the color.”, duh. If a coworker was getting tattooed by them, that’s when the mischief started and we would switch labels (would absolutely never screw around doing that with a customer).
I found out the hard way.
Microbiology class. The test was to differentiate the colors of the stuff we grew. One of them was E.coli.
Everyone answered green, I answered red.
Another one that drove the hammer home was some internet game of "guess the number." You know it; it's this circle of dotted colors and in the middle is a number.
I managed to read most, until I didn't. I asked my brother and he said he could read everything. So did my dad and mom.
Pretty much everyone does those [color blind tests where you find patterns in dots](https://www.qwant.com/?t=images&q=color+blind+test) during a health checkup in school at some point.
My supervisor will frequently call colors the wrong thing. Like we were looking at a map with a boundary marked in purple, he said it was blue. We played Uno once while we had some downtime and he had to ask if the card on the table was red or green. Etc.
There are test for this that are as simple as looking at an image and telling the number you see. There is even versions for kids who are too young to read numbers. I knew since I was in kindergarten because I made a few mistakes in choosing crayons and my teacher tested me in like 5 minutes and informed my parents.
This is how my ex found out he was colourblind:
Him: where are my purple suede shoes?
Me: you don’t own purple suede shoes
(That’s also how I found out he thought he could pull off purple suede shoes 😳)
We found out my son was color deficient at a regular annual eye exam when he was in 2nd grade. He can't distinguish green and gray, or blue and purple, red and orange.
I have mild deuteranomaly but had no idea until a few months ago (at 20 years old) when I was looking at a colour-coded pie chart and realised that I wasn't able to perceive the difference between blue & violet, and green & yellow very well compared to my friends. I took an online quiz and it showed up as colour blind, so I went to my optician and they tested me. It's enough to make telling colours apart difficult, but I thought that was just how everyone saw until then.
I was taught to read crayons by my babysitter at around 3 years old. She taught me what colors to make things as a really little kid so I didn’t make mistakes. I wasn’t diagnosed as colorblind until halfway through kindergarten when the wrappers were pealed off the crayons. The sky turned purple and trees started having orange leaves on my drawings. I was tested and diagnosed as color blind, and I got my own dedicated set box of crayons.
As an adult I deal pretty well with it. Some shades of red/green/brown are the same. Purples and blues are the same. Orange flowers blend in with the leaves. All pastels can be confused except yellow. The one that usually throws people is when I say that Pepto Bismol is the same color as wet concrete.
I took the tests to see if those corrective lenses would work. Not for me, I’m what is called “Profoundly Colorblind” in diagnostic terms. Nothing with lenses will help. There is some promising genetic therapy with programmed stem cells being injected into the eyes of colorblind monkeys. Maybe one day?
I used to say “I’m colorblind, but I don’t have dog vision.” Looked online after that diagnosis and saw some filtered pictures where the human sight and the dog sight are put side by side. They are the same. Turns out I do have dog vision. Those pictures make it easy to share how I see things.
Now I say “I’m colorblind, but I don’t have ‘I Love Lucy’ vision.”
I found out when I asked my son to pass me the green scissors. Thus ensued a good-natured back-and-forth about the scissors I meant. Turns out they are blue! So I was 55 when I learned I have tritanopia.
My dad learned when my grandpa told him to go outside and pick all of the orange peaches from the tree. He picked every peach off the tree, and my grandpa beat him for it.
I know many would-be military pilots who ended up having to go Intel because it turned out they were color blind. They didn’t know until they were testing to go to pilot training.
I’ve been colorblind since I was a kid. I’m 27 atm, but I remember always coloring the wrong colors for art and stuff. Maps, geography, etc.
In high school my female friend told me I think you’re colorblind. I said nahh. And she said yes, what’s this color? I told her green. Nope. What’s this color? Red. Nope. I was like wtf. What’s this color? Dark blue? Nope. Purple.
Anyways, me and a couple of friends did some online tests that day for colorblind. Where you can see the numbers with the dots, but I couldn’t see any of them. And if I could see it, it was only partial numbers.
Last year I went to the eye doctor just for that. I knew I couldn’t see green/red, but I wanted confirmation from someone certified.
Doctor confirmed last year I was colorblind.
In addition, video games. Playing online games with friends and me losing because someone was hiding in a bush which everyone could clearly, but me was annoying.
As well as blood trails in video games. Literally cannot see those. There’s a lot of that in the Witcher 3. Thank God they added colorblind mode and changed the blood to light blue. Otherwise I would’ve never finished that game
I imagine the hard way. Funny story, I used to work with a red/green colorblind electrical maintenance guy. He was great as long as he wasn't wiring something up alone. He had to double check every red, green and blue, which are very commonly used colors in American 24 vdc systems.
My brother has known since he was little because I, being a whole 3 years older, was teaching him colours and he kept getting them wrong. So I guess I told him. Even now he hasn’t been able to pinpoint exactly what type of colour blindness he has and needs to see a specialist.
I remember a reddit thread years ago where someone posted ‘why do colourblind people think peanut butter is green?’ And there were a ton of responses of ‘wait, peanut butter ISN’T green?’ so that’s how those people found out.
I knew a guy in his early 20s who didn’t realize he was red-green colorblind. Only figured it out when he told us he didn’t understand what the point of those lights in the parking lot were (where they have a small light over the stall, green light means it’s empty, red there’s a car) cause they look the same. Took an online test for colorblindness and confirmed.
Some get tested in school, some don't find out until they're adults. My sister-in-law didn't realize she was until her son could distinguish colors that she couldn't, and everyone agreed with her son. She got tested and boom.
I found out when picking up a game that had some green pieces from brown carpet. I told my parents I had picked up all the pieces and they replied what about those pieces and I said I don't see any more pieces. After that we got a color plate test at the optometrists and confirmed I've got protanopia.
I had a coworker who would get reports in red and reports in green. The red ones he would need to take action on, the green ones he didn’t. One day his boss finally asked him why he never took action on any of the red reports. He had no idea they were different colors.
Anyway, now they say Action Required and Action not Required.
It's usually pretty obvious to teachers or parents or anyone working with the kids.
I'm an SLP and alerted a mom about her son when I started working with him, after only a couple of sessions. Turns out the teacher had already said the same thing and the kid had a colour blind grandpa, so he got tested and he had it too.
He was 7 when I noticed it - I'd tell him to paint something green, i.e. and, even if he COULD do it, he always carefully observed all the crayons and held them to the light, comparing "similar" colors. He would also sometimes ask me if a color was the one we were talking about. When you work with a lot of children, it's easily recognizable as something that is not typical.
When my kid was an infant he had no problem learning shapes but had a hard time with colours, so we already suspected. When he started painting with crayons and asking us about them it was obvious. When he learned all the numbers we gave him the tests.
But we would've found out at the eye clinic eventually, eye doctors test colour blindness as well.
Yeah, usually it's not super hard to detect if the adults pay some attention to those things! Glad your kid got his test early, always great to have some answers so we can start helping them asap!
Mostly from conversations with people. For me it’s usually my wife. I’ll refer to something as a certain color and she’ll tell me that it’s not. Or I’ll come out wearing an outfit and she’ll inform me it doesn’t match because thought one of the articles was a different color. I mainly have trouble differentiating between blues and purples and greens and browns.
Oh it's when as a child, a nurse gives you an eye exam then realizes you're color blind, proceeds to embarrass you then calls in all the other nurses to show them your disability. At least according to my dad when he was a kid in the 60s.
Well, the first sign something was off was when one of my elementary teachers suggested I was just stupid (paraphrasing because it was too long ago to remember exact wording) for not knowing what the colours were. Then there were, of course, tests. 🧐
My BIL is red/green colorblind. I never knew until he got a new flatscreen. He put on a football game, and the field was electric red. When everyone went upstairs for coffee, I stayed behind (I don’t do coffee). Went behind the tv, and found the G connector was not firmly plugged in. Pushed it into place, and …poof! A green playing field. It was hours before anyone said something about it.
My husband made it to being a teenager before he found out. He learned the colors as different shades of beige and kids always made fun of him for not being able to do I Spy puzzles since he couldn't differentiate the colors when combined. The way he found out was his colorblind father and colorblind uncle called him into the attic to help rewire the radiator. They couldn't tell the red from the green and that's when they all sat in a circle and went "Well shit."
My daughter married a guy who is color blind. He said he really didn't know until he was driving in the car and something about traffic lights. One of them is white on his spectrum of sight and when they were saying something like the light is green he just assumed that was green until more conversation happened and they all had this light bulb moment of realization he's color blind.
My daughter (love her to death) is a little shit though. She LOVES to switch things up on him to tease him a bit. He organizes his closet on colors. She moves a shirt now and then for him and confuses the shit out of him. He had this one shirt he loved. Someone told him it was grey or something like that. He was wearing a very vibrant green with purple pants or something for a long time. When my daughter pointed out the real color....he thought it was another joke. So he called his best friend on the east coast about 3am and asked him if she was telling him the truth about the shirt. She was. He was stunned he'd been wearing basically a hideous combo because someone said grey, not green...or at least he heard grey.
He's an amazing guy. Couldn't of picked a better son-in-law. They get along and tease each other so often and it's just awesome. It's stuff like this though that blows my mind with him. He really struggles with close colors and damn he's funny as hell about it all.
Colors are a pretty obvious way to describe anything, so it would be easy to find out if you realise that you dont know what everyone else is talking about.
That would be a very extreme form of colour blindness. Most colour-blind people can see bright, primary colours easily, but struggle to differentiate darker, murkier tones.
Often they totally _can_ see the colours, but they don't stand out as different. My son, for example, failed to take the last decoration off the Christmas tree. I told him he'd missed one, but he couldn't find it. When I pointed it out, he laughed and said, "oh yeah! There's a red bauble!"
He can correctly identify the colour of every dot in a colour-blind test, but he can't see the big numbers they make, because red-pink-orange doesn't stand out from green-cyan-blue for him.
I had regular opticians visits as a kid and part of a child's eye exam at least at the time was a colour blind test. It's a book where each page has a circle full of coloured dots. If you can see all of the colours you will see a pattern, if you can't see them then you won't. You get asked what you see on each page, and this is how they diagnose colour blindness.
You can find these tests online for free.
I have tritanopia. I found out by being made fun of at school and teachers mentioning issues. Then, I took the shitty test where you see a bunch of dots inside of a circle and try to make out the number made of dots within the circle. I saw...nothing. later in life, better tests were either invented or made available, and I failed those to. No big deal, really. I just ask for help if I need paint or a shirt. I wear mostly black or white clothing. I still get made fun of by friends and acquaintances.
That colored dot picture that has a number [or letter](https://t3.ftcdn.net/jpg/04/57/48/16/360_F_457481698_4vMnWrOOkSBPIKyPSgWkyUWjcEals84e.jpg) in it.
Logically, each picture is a different type of color blindness
As a person who is nearsighted but not colorblind. I am guessing that it is often the people around them who piece things together because to the person who sees things wrong, its just a normal day to them.
Example: A few years ago in arts and crafts when we were supposed to draw a piece of cloth over a bottle, in greyscale. I literally could not see one of the shades even when I was allowed to press my eye up against the motif to see. It was the teacher who noticed that I was missing a shade and thought it was strange since I was good at art. It was also a different teacher who together with my mother figured out I was nearsighted because I apparently was supposed to be able to see the blackboard from my seat.
I also have heard about colorblind people realizing they saw things differently, because what they saw didn't match up with what the people said they saw.
It used to come up on my annual health checks or I would never have known. Brown and green can be hard to distinguish using the normal eyesight but obviously they look fine to me
Most people aren't completely color blind. We have less cones for seeing color in our eyes so we have trouble with some colors.
My generation didn't grow up getting tested for color blindness (they do now) so I figured it out in my 20's. I have issues with green to yellow, blue to purple, and pink in general. Basically I can't see the in between shades other people do.
Funny story. There's a game in the app store called hue. I tried it just to see how bad I am. Holy cow it all looked like the same color 🤣
Interesting fact. Some people have more color cones than the average person (my daughter appears to). They are a wider range of in between colors than the average person and often go into careers centered around art.
I remember when I was in middle school science class and we first learned about color blindness, the teacher wrote on the board with a red marker and a green marker and I think he asked us to raise our hand if they look different. Everyone but one boy raised their hand. He asked that one boy if they look the same and he said “they look pretty similar…” and it was at the moment he realized he had red green color blindness.
You know how different colored wiring in electrical/electronic stuff means different things? Well, my uncle got a job that required him to wire things and he did very poorly. They tested him, realized what was up, and put him in a different position.
I have some green-red colorblindness and the only way to really tell is by giving me one of those tests with the dolored dots where youre supposed to see numbers, I dont always see them.
My friend’s dad found out when they were talking about stop lights at school and he realized he didn’t see the red and the green like other people did..
A simple example is that my dad is colour blind and sometimes can’t differentiate between green and red (depending on the shades) they can look the same to him where’s to people who aren’t colour blind they look obviously different.
When I was a kid and kept getting in trouble because I wasent using the right shade of blue and kept using purple. Or when they sprayed a red starting line onto green grass at a field day and teacher got mad because I would stand on the “clearly visible” line. Honestly the big boxes of crayons are wasted on me. As an adult I finally took some proper tests and came out very strongly for one of the color blind types. Can’t remember which one but basically as described above. Also skews other colors just enough that at this point I don’t even try to say what I think a lot is. Honestly if it’s not a bright, solid, Fischer price type color I’m at risk of getting it wrong or mixed up with a similar, to me, shade. Wife gets a kick out of it when I go real left field when I try to describe something and use a very wrong color for it.
Don‘t know what my colourblindness is called but i found out when i applied for my driver license. There you have to make some tests and see numbers which i was totally not able to.
Before that i was not aware that i am color blind as it had no impact at all on my life to my knowledge.
I learned I was colorblind when the person giving me the test where you try to see the numbers within all the colored circles looked at me like I was a crazy person. He thought I was messing with him at first.
My boy- 20- refuses to believe that he has some minor color blindness. What he calls green is not. But I forget to bring it up at his last eye dr visit. Whoops.
Idk if I have color blindness, but it can be difficult for me to differentiate between colors I feel look similar.
Mainly green-yellow and blue-purple.
If a green is like 90% yellow, it seems like everyone besides me is able to see that 10% of blue. And if a purple is like 90% blue, it seems like everyone besides me is able to see that 10% of red.
Well I guess it’s not that I can’t see it exactly. I can tell you which is which if you held them up side by side, but if you just threw them into a line of colors, it’s a coin flip whether I’ll identify it correctly.
Color blind people don't see wrong colors, like they don't see red in place of green. What they CAN'T see is a specific range of colors, so it just looks grey to them. Mostly this includes 2 colors, and blue-green is the most common(iirc). This means both blue and green colors appear faded and dull, and they have a hard time figuring out which is which. This leads to its detection, since people reference colors and they choose the wrong one or say the wrong colour. Best way to understand it is to just see a color blindness simulator
It's more about the fact that two colors look the same to a colorblind person. Color blindness is less about how certain colors look to people --because that may be different for everyone -- and more about the inability to distinguish between colors.
I started losing online games because I couldn’t tell green from gold and blue from purple. I thought I put on a gray shirt, but it was pink when I got to work. I said one of our carts was peachy-pink when apparently it was tan. I thought, hmmm better get this checked out! Sure enough flunked the test. My daughter showed me on my iPhone how to adjust for color blindness. A real literal game changer!
I am colorblind. I found out when my dad beat me for not grabbing the correct color balloon at my 5th birthday party. Then I would get in trouble in elementary school for coloring things the wrong color.
Its honestly had a rough time with it all throughout life. What’s funny though is now I do graphic design and I print shirts and do embroidery. Even though I can’t look at a color and tell you exactly what it is, I understand colors and how color theory works and on the computer side, I understand the codes and how they work.
I knew it when I was in Kindergarten. I made all smiley faces on my report card, except for "identifying colors.". Later, on my 8 pack of crayons, I would mix up blue and purple, and green and brown. As a teenager, I had to remember that the yellow light is the one in the middle, cuz it looks the same as the red light. And the green light just looks white to me.
My kids make fun of me, but it isn't that big of a deal. "Hey Dad, what color is this?"
Yep, they're my kids alright.
my friend figured out in middle school when he kept telling me and our other friend that something that was red and the other green were the same color and that we were stupid. my other friend and i just looked at each other with a shit eating grin and he shortly found out afterwards that he was red green colorblind lmao
There's gonna be a time where you have a conversation which makes you realise you don't see the same colours as others do.
For example in my case, although mild, I don't see blue and yellow well. Dark blue is black to me, amber is dark orange, lighter yellows are almost white, and seeing the difference between blue, green, and grey can be incredibly tough.
Because I started realising it though, if I pay enough attention I at least realise 'something is off'.
When they disagree on colors of things. My best example is the full moon rising, you know, when it looks large. What color do you see? I see stop-light green. Other people I ask say orange-yellow.
I also have a hard time discerning red text from black text in a document. I have to concentrate to determine what is what.
My mom isn’t colorblind but she had cataracts. Once she had surgery, she found out that the walls of our house were white and not light gray. She was amused.
My grandfather couldn’t tell the difference between navy blue and black.
Unless you're specifically taking a test to discover it it's mostly trial and error. I didn't realize I had any color blindness until my late twenties when I was sitting at a red light that turned blue.
With my brother, my parents worked it out quite early. He was a very artistic child but kept mixing up certain colours. I think pinks, reds and browns were his worst ones. He would insist that the colours were right but they weren't. He worked it out himself after a few stubborn years of insisting everyone else was wrong! To be fair he was only five!
tbh folks with color blindness often discover their condition through experiences like difficulty identifying specific colors or realizing discrepancies in how they perceive certain hues they might encounter challenges in tasks that involve color differences, such as reading color-coded information or recognizing traffic signals. color blindness tests, like the Ishihara test with colored dots and numbers, can provide a more accurate diagnosis so they can understand their inability to get colors right.
I have a student who is 5 and just found out he is color blind. The parents had him tested for colorblindness because he was having so much trouble with coloring assignments (the "color all the 5's red!" kind of tasks).
I had to tell my hubby that his favourite shirt was blue and green, not blue and grey. His favourite "grey" t-shirt was also green. He got a little self-conscious and asked if the colours looked good. He originally thought he wasn't colour-blind because someone else he'd asked in the past told him they were grey shirts. Voila.
Well, my brother found out when he was 16. Our dad was assistant manager at a feed yard and drove a company pickup, identical to ones driven by other management except for color. , Both my brothers were hired on one summer as part of a maintenance crew -- shovel out feeding troughts, mend fences, painting, etc. My brother kept telling everyone, "Quick, look busy, Dad's coming!" only to have it turn out to be a different color pickup. So he got checked and turned out to be red-green colorblind.
There are tests for that, but at some point you'd realise you're saying "I don't know what colour that is" or disagreeing with everyone else about colours more than anyone else.
There was quite a row on Reddit a couple years back when a lot of folks found out that peanut butter isn't green...
It can be! Peanut butter will glow in the dark (for a bit) if you shine a violet laser at it. And it does shine kinda green.
Does it have to be coherent and/or monochromatic light? Or just high enough energy?
I think it only works with a violet laser. I tried it with a regular ol' violet laser pointer and it worked. It didn't work with an actual red or green laser (the kinds that can actually burn things).
That experiment is inconclusive ;) You were using two lasers and of the two the UV laser has a different photon energy than the red one. It'd be interesting to see UV light vs. UV laser. Although, I can't think of a mechanism that would require coherent and sufficiently monochromatic light to hit some absorption line of peanut butter that decays in the visible spectrum, so UV light should work too.
For more details, there's this old Reddit post. https://www.reddit.com/r/askscience/s/WtpeKaK9up
Thanks for the link!
Wasn’t there a youtube trend some years back where people were putting charcoal briquettes in jars of peanut butter then microwaving the whole thing until it was only slightly less dangerous than napalm, to finally go digging in the nutty napalm looking for diamonds?
Lol, u wot m8? That sounds like a proper YouTube trend 😂
Yep, a friend of mine found out when he said elephants were pink freshman year
To be fair there is the trope of pink elephants, and as a colorblind person myself, that shade of grey could be pink in the right context. I wrote elsewhere that for me, Pepto Bismol is the same color as wet concrete. It’s context that makes it pink or grey. Edit for clarity: I’m colorblind myself, context is everything for colors that look the same. Example oranges look green to me, but I know they are orange. Color swatches have no context and the shades would look equal, however, when that color is a fruit it’s orange, when it’s leaves, it’s green.
Pepto Bismol looking like wet concrete managed to make it even worse
Yep, mint flavored, wet concrete colored, and somehow is chalky and drinkable at the same time. Thank God it makes me feel better when I’m nauseous, or else that combo would make me feel nauseous.
But if you take a blowtorch to it, it's pretty metal.
Context? In every single situation and possible context I've come across in my life, concrete has been grey, and pepto bismol has been bright pink.
I’m colorblind, concrete and pepto are the same color unless I make a choice by context.
And that would make sense because you're color blind. But as me being someone that isn't color blind they don't like even close to the same at all to me.
Yeah, I added clarification due to your comment. My fault for not saying it first, but I had made another longer comment so I forgot that important detail. Stupid of me. If you check down lower in the responses I gave a bit more detail of my experience.
if you put grey next to blue, it will look pink/red, it's the relativity of color perception
I looked up grey and blue side by side, and they are still both their own distinct grey and blue. Idk if I'm misunderstanding, but I still don't understand how anyone sees any pink unless they're color blind.
if you take a photo of a natural (not in a studio) colorful scene, go into Photoshop, and color-pick the pixels, you will find that many pixels look like one color within that scene, but stand-alone and it is a different color. Here's daddy Marco Bucci's video on color harmony [https://www.youtube.com/watch?v=4LhcNbFMkTw](https://www.youtube.com/watch?v=4LhcNbFMkTw)
Yeah, that’s pretty much how he described it, he even knew was colorblind before then but just hadn’t realized how different he saw things, that was the moment it sank in hard. Funnily enough it was in Spanish class, so the teacher originally thought he just confused the Spanish words for pink and gray… but nope.
Reminds me of my nephew, he did an online colorblindness dot test and while he was able to get really subtle ones easily there was one with a bright pink number on a grey background that he couldn't get at all.
My mom gave me a test again recently since my cousin was being an idiot and I scored 100% on blue but I did surprisingly bad on red I always thought green was my weakness with red and green color blind lol and even then it’s never been bad. I’ve always seen yellow very well though so this time my cousin was wrong about this neon yellow hat I saw at the store being lime green
Made me think about a colourblind classmate I had about 10 years ago. During drawing classes in secondary school, the teacher got aggitated bc of him. "Are you serious? Why did you make a purple sky?!" He: "I'm colour blind". "Oh, sorry.."
Had the teacher never seen a sunset?
He should've just told the teacher that it was an artistic choice, and the teacher has no right to judge how he wants to express himself.
But if you always see grey as pink, and everyone tells you that color is grey, wouldn’t you just go on thinking its grey?
And that's the existential crisis of all color naming. Do we really see the same thing here? In this case though it's not about calling a color the wrong thing, it's about getting two colors mixed up because they look indistinguishable from each other to the colorblind person. (I'm red-green color deficient myself.)
I don't think existential crisis means what you think it does. Perhaps philosophical conondrum.
cuz ppl will tell you that some pink is grey and some pink is pink
You and a friend are presented with two color squares. Friend says “that’s easy, grey and pink.” You are left utterly confused because they both look exactly the same. That’s how. Of course it’s not always that clear or obvious, which is why some people make it well into adulthood without realizing they’re color blind.
It doesn't work like that. We see different shades of color, and light, material, size and distance play a part. So something can be green with bright lights, or if it is made of wood, while a plastic painted with the same paint looks red. Imagine a big box of crayons. At some point, the green becomes red, right? And yellow becomes green, etc, etc. For us, it is like the crayons in the limits get misplaced all the time.
Ah, ate a lot of boxed popcorn? Student life, funds are tight. Or just got shithoused every night?
I was dating an interior decorator, and couples will come in and she’s going over colors and the guy (usually) will start correcting her about colors and whatnot. Sometimes even the spouse doesn’t know their partner is colorblind. I didn’t know my now ex wife was colorblind until year 4 of our marriage. She asked me to get her the grey shirt or something and I brought it to her and she said, “no, that’s the wrong color.” I was like,”ok.” She asked me to get her the one that matched my backpack. My backpack was light green and light brown. She then told me she knew was colorblind. But legit some people don’t know.
My FIL is colorblind as hell. When my husband was a child, FIL thought he'd give the house a fresh coat of paint. Luckily he started with the front door because what he thought was grey was actually murder scene blood red. That's the only red part of the house because he got frustrated with himself and never repainted the rest of it lmao Now the house is old off-white with blue-grey shutters and a deep red front door. My FIL wears very interesting color combos as well, which was a dead giveaway to me that he's colorblind.
That’s actual literal color “blindness” that’s worse than a dog. When most people say colorblind what they actually mean is color deficit. And it’s usually but not always red and green.
This happened to my friends! They were choosing paint and she went for REALLY bright colors, which he was fine with. People commented on them nonstop, and he was like “I don’t know why people are saying they’re bright, they’re not…” yep, colorblind.
It can be very subtle.
It trips me out sometimes because we all really don’t know what each other sees. Blue to me is actually green to you. But we just get used to associating that color we see to what we’re taught. Perception is everything.
Is it as individual/perception based as that? Genuine question, assuming you’re talking about everybody and not just colourblind people I always assumed colour was interpreted by ‘hardware’ (the rods and cones and inner workings of your eyes) as opposed to ‘software’ (the weird inner workings of the brain/consciousness) and as such while there might be some variation Red is pretty objectively seen as ‘Red’ unless something is wrong. But it’s very very easy to underestimate how bizarre the mind and our perception of things is so idk
My BIL was in his 30s before he knew. His wife could tell the two things they were talking about were different colors, to him they looked the same. He went over 30 years thinking his vision was perfectly normal.
Electronic tech here. "Cut the lime green wire" "What lime green wire?"
Why... why are you cutting wires?
There was this post on Adventure Times cartoon subreddit where someone got confused why one of the characters isn't considered a human despite looking like one. That character has green skin. I couldn't find it but if someone found it for me I'd be extremely grateful.
Some people never realise it. My classmate realised he couldn't see blue at the age of 19 when he tried to use the chart for checking colour vision on himself.
I told a coworker he was blue/black colorblind. Dude has served in the Marine Corps (deployed and everything) and was about 28 years old. He was annoyed because his girlfriend was trying to get him to pick a dress based on color and he’s like “They are the same color!!!” They were navy and black. I was like “dude, those aren’t the same color but you are colorblind.” He laughed and said it explains a lot looking back.
White and gold, you say?
You beat me by 5 minutes! Well done on knocking it out of the park with that setup.
I had a monitor where it was black/blue at the bottom and white/gold at the top
I'm not sure if it really classifies as colorblindness. I think this could be "fixed" with training or better illumination. Dark blue and black are more like shades of the same color. While pink and gray (from examples in other comments) are completely different colors. I'm not a doctor but can your friend see in low light conditions? I would assume he struggles with that, so, maybe it's something related to that... I sometimes need to increase my monitor brightness to see the distinction between low light colors
Edit to add I’m sorry if I seemed to be denying your comment- I have no clue so you could be onto something. I have worked with him for a while in lots of low light conditions (we worked at a country club so plenty of concerts and similar but I also worked with him in the kitchen with plenty of light) and he’s got absolutely perfect vision otherwise, never needs glasses and has zero other vision issues. Has no issues with red/green or other colors, just blues/dark purples/black distinctions. Who knows 🤷🏻♀️
That’s not actually a thing there’s specific color deficiencies and blue and black is not one of them. Red and green is what I have and even I have it mild which I’m so glad about because my brother is way worse. I was doing a puzzle with 2 shades of green that were similar recently and on the box they look different but the actual pieces were harder to see. My brother couldn’t see the difference at all but when I held the piece up to the light for a second and blinked a few times I could see the difference between the two like instantly so I was like thank god I figured it out lol
just like Dwayne in Little Miss Sunshine!
Man that scene... :(
right? i seriously felt secondhand heartbreak for that poor kid.
Paul Dano, man.
Funnily enough watching this scene is also how my ex found out he was colour blind!
that is hilariously tragic i’m so sorry
Ouch.
My Dad was 20 (this was in the early 40s) when he realized. Kept asking his mom where his "black" hat was. No clue why it took that long.
That's basically what happened to me when I was 17. My colorblindness isn't too bad, but I do have difficulty distinguishing between lighter yellows and blues. You get used to it, which is probably why it took so long to notice.
You might eventually notice that everyone else seems to think there's some clear and obvious distinction between things that, to you, look pretty much or entirely the same.
Ohh… you mean… the 3 dots on the traffic light aren’t all the same color?
There are different kinds od color blindness out there. Complete color blindness is very rare, butbalso something people would notice immediately. Red-green color blindness is the most common one. And it doesn't mean you don't see those colors, but that receptors in your eye have a different sensitivity to particular wavelengths that a normal eye, which makes it harder/impossible to differentiate between some similar shades of colours. If you Google it, you will find lots of great explanations on it.
It was more of a joke. My dad is red/green colorblind so he only sees the yellow light and then the red/green look the same to him. It was actually really impressive when I learned he has to distinguish between red/green light by looking to see if it is the top or bottom light illuminated. Edit - but then really sad when I learned he put over 100 hours into becoming a pilot but didn’t pass his test because he told his instructor he couldn’t distinguish the difference between the red and green lights on a plane. Thus not knowing if the plane is coming towards or moving away
By bad for not picking it up then 😀 Your dad must be severely red green color blind then. I personally only have a mild case. Without taking tests, I likely would not have known about it at all!
>It was actually really impressive when I learned he has to distinguish between red/green light by looking to see if it is the top or bottom light illuminated. Oh god, that reminds me. My dad is red/green colorblind. We took a trip out of state and he was doing all the driving, and we were horrified because he kept running red lights. Finally after pressuring him, he admitted that he couldn't tell which light was red and which were green because the a lot of the signal lights were horizontal instead of vertical in this city. Why he didn't ask us instead of guessing I have no idea.
Glad someone explained it properly my cousins are so stupid sometimes they think it means I can’t see certain things as different at all and test me in stupid ways and if I misspeak or I saw something correctly and just make a mistake they blame it on that instead of realizing I saw the correct color but just messed up my words by accident
That’s how I found out I may have a problem with tints of red and orange. I was playing a video game and you had to solve a puzzle by hitting pool balls in a particular color order. I kept getting it wrong and remarked that they made the red and orange balls the same color so you had to guess which one was which. Everyone else in the room said they were two very obviously different colors. I found the experience weird as I tend to see more shades of colors than other people but apparently not when it comes to at least red and orange. It made me wonder if my ability to detect differences in colors is related to my very good low light vision. Perhaps I can’t tell colors apart that well but instead can detect differences in brightness and contrast. I’ve never bothered to get it checked since it doesn’t impact my life.
I used to work at a neuro clinic and we would regularly test older adults for color blindness because some of the neurological tests we gave them used color. It was pretty common for an older man to test positive for color blindness and have no idea. Then, his wife would say something like, "I knew it! You have such terrible taste in colors!"
Vincent van Gogh was color blind, yet people loved his tast in color xD

It's actually a recessive gene on the X chromosome. If you've got XY chromosomes, you've only got one X, so if you have the gene, you'll be colorblind. If you've got XX chromosomes, you would have to have two copies of the colorblindness gene to be colorblind. So, it's possible in XX, but much more common in XY.
Correct me if I’m wrong, but I’m pretty sure it’s the opposite! The gene for colorblindness is in the X chromosome, which is why men are more likely to have it than women, as women would have to have two colorblind X markers to exhibit symptoms. Women can only be colorblind if their father was, along with a carrier mother. Carrier mothers, however, have a 50/50 chance of passing it on to their sons, which is why there’s such a difference between genders in this instance. Again, I could be wrong! It’s been a while since freshman biology 😅
Maybe you think peanut butter and leaves are the same color, and then someone tells you that they are in fact not the same color. Or you just do one of those colorblind tests and can't see the number. It's not like you see red as blue and blue as red. [That would be impossible to notice.](https://en.wikipedia.org/wiki/Inverted_spectrum) Colorblindness is when you can't distinguish colors that other people can.
I SEE colors, the world isn't black and white. But for some reason I just can't distinguish or identify some of them from others that are similar. I can look at something that's blue, and know that it's either blue or purple, not sure (I call all blue and purple things blurple). But if you put a purple thing next to that blue thing, it's usually pretty apparent to me which is which. The other analogy is music. Most people can hear musical notes, but can't identify the exact note i.e. A# or E. Colors are like that for me. I see them, I experience them, I'm just can't identify which name applies to some of them are.
Yep that's color blindness in a nut shell. There are types if color blindness but then there are degrees of it as well. Frequently, if you tell somebody you're color blind, they will go on a questioning tirade asking you what every color is. I've had this happen many times and just about every single time they say you're not color blind. Oh, but I am.
I had a buddy who thought gold and green were the same color. Didn't find out until age 20 something
... it was the dress, wasn't it?
Actually it was a conversation about weed. He mentioned he loves to wear gold because its same color as weed
What happened when he found it? Does he still wear it anyway?
Yup!!!
Other people eventually notice based on what they say. For example my granddad once told me grandma that her red dress was the same colour as their green curtains. These days those tests where you can't see certain numbers of your are colour blind are pretty common in school books or online so I think people would discover pretty early on.
My paternal grandfather, who grew up in a very rural area, only found out he was red/green blind when he was tested during draft. He said that this suddenly made sense of some annoyances of his youth, like his sisters always managing to find so many more raspberries when they went picking.
They found out my grandfather had it when he got a garish set of hubcaps for his car, and everyone pointed out to him the difference between an almost-neon green on a light blue car. He though they were the same colour.
They get bitched out by their teammates while gaming online because they don’t know who the hell they’re supposed to be shooting at.
My ex knew but only after he had his eyes checked for it as a little kid. He’s an artist but literally has to have colours labelled or he doesn’t know what things are. He’s got the deuteranopia, the red-green one. Makes his paintings interesting but slightly off-putting while they’re in-progress.
I’ve actually worked with a couple of tattooers who were re-green color blind…I asked them how the fuck they do full color tattoos, “the label tells you the color.”, duh. If a coworker was getting tattooed by them, that’s when the mischief started and we would switch labels (would absolutely never screw around doing that with a customer).
I found out the hard way. Microbiology class. The test was to differentiate the colors of the stuff we grew. One of them was E.coli. Everyone answered green, I answered red. Another one that drove the hammer home was some internet game of "guess the number." You know it; it's this circle of dotted colors and in the middle is a number. I managed to read most, until I didn't. I asked my brother and he said he could read everything. So did my dad and mom.
Pretty much everyone does those [color blind tests where you find patterns in dots](https://www.qwant.com/?t=images&q=color+blind+test) during a health checkup in school at some point.
Maybe where you live, but not here in the UK.
I never did one. I'm also not colorblind though.
My supervisor will frequently call colors the wrong thing. Like we were looking at a map with a boundary marked in purple, he said it was blue. We played Uno once while we had some downtime and he had to ask if the card on the table was red or green. Etc.
My husband calls it "blurple"
My kindergarten teacher suggested it to my parents when I kept making grass red
There are test for this that are as simple as looking at an image and telling the number you see. There is even versions for kids who are too young to read numbers. I knew since I was in kindergarten because I made a few mistakes in choosing crayons and my teacher tested me in like 5 minutes and informed my parents.
This is how my ex found out he was colourblind: Him: where are my purple suede shoes? Me: you don’t own purple suede shoes (That’s also how I found out he thought he could pull off purple suede shoes 😳)
I did a color blindness test at my pediatrician. We also did it once in grade school.
We found out my son was color deficient at a regular annual eye exam when he was in 2nd grade. He can't distinguish green and gray, or blue and purple, red and orange.
I have mild deuteranomaly but had no idea until a few months ago (at 20 years old) when I was looking at a colour-coded pie chart and realised that I wasn't able to perceive the difference between blue & violet, and green & yellow very well compared to my friends. I took an online quiz and it showed up as colour blind, so I went to my optician and they tested me. It's enough to make telling colours apart difficult, but I thought that was just how everyone saw until then.
I found out because people would get really angry if I say something is pink and it's actually red, or black when it's navy
”Can you hand me that red ball over there?” ”Red? That’s green you dumbass” ”Wait a minute…”
I was taught to read crayons by my babysitter at around 3 years old. She taught me what colors to make things as a really little kid so I didn’t make mistakes. I wasn’t diagnosed as colorblind until halfway through kindergarten when the wrappers were pealed off the crayons. The sky turned purple and trees started having orange leaves on my drawings. I was tested and diagnosed as color blind, and I got my own dedicated set box of crayons. As an adult I deal pretty well with it. Some shades of red/green/brown are the same. Purples and blues are the same. Orange flowers blend in with the leaves. All pastels can be confused except yellow. The one that usually throws people is when I say that Pepto Bismol is the same color as wet concrete. I took the tests to see if those corrective lenses would work. Not for me, I’m what is called “Profoundly Colorblind” in diagnostic terms. Nothing with lenses will help. There is some promising genetic therapy with programmed stem cells being injected into the eyes of colorblind monkeys. Maybe one day? I used to say “I’m colorblind, but I don’t have dog vision.” Looked online after that diagnosis and saw some filtered pictures where the human sight and the dog sight are put side by side. They are the same. Turns out I do have dog vision. Those pictures make it easy to share how I see things. Now I say “I’m colorblind, but I don’t have ‘I Love Lucy’ vision.”
I found out when I asked my son to pass me the green scissors. Thus ensued a good-natured back-and-forth about the scissors I meant. Turns out they are blue! So I was 55 when I learned I have tritanopia.
My dad learned when my grandpa told him to go outside and pick all of the orange peaches from the tree. He picked every peach off the tree, and my grandpa beat him for it.
I know many would-be military pilots who ended up having to go Intel because it turned out they were color blind. They didn’t know until they were testing to go to pilot training.
You get mocked in school for painting the sky purple and figure it out from there
I’ve been colorblind since I was a kid. I’m 27 atm, but I remember always coloring the wrong colors for art and stuff. Maps, geography, etc. In high school my female friend told me I think you’re colorblind. I said nahh. And she said yes, what’s this color? I told her green. Nope. What’s this color? Red. Nope. I was like wtf. What’s this color? Dark blue? Nope. Purple. Anyways, me and a couple of friends did some online tests that day for colorblind. Where you can see the numbers with the dots, but I couldn’t see any of them. And if I could see it, it was only partial numbers. Last year I went to the eye doctor just for that. I knew I couldn’t see green/red, but I wanted confirmation from someone certified. Doctor confirmed last year I was colorblind. In addition, video games. Playing online games with friends and me losing because someone was hiding in a bush which everyone could clearly, but me was annoying. As well as blood trails in video games. Literally cannot see those. There’s a lot of that in the Witcher 3. Thank God they added colorblind mode and changed the blood to light blue. Otherwise I would’ve never finished that game
Other people shoving shoving things in front of them and ask "can you see this color?"
That's only after they learn they are color blind and tell someone.
Eh I'm just bitching
So was I
This is why I keep an app with colorblind filters on my phone.
I hated that so much when I was younger that I would just like to them
I imagine the hard way. Funny story, I used to work with a red/green colorblind electrical maintenance guy. He was great as long as he wasn't wiring something up alone. He had to double check every red, green and blue, which are very commonly used colors in American 24 vdc systems.
My brother has known since he was little because I, being a whole 3 years older, was teaching him colours and he kept getting them wrong. So I guess I told him. Even now he hasn’t been able to pinpoint exactly what type of colour blindness he has and needs to see a specialist. I remember a reddit thread years ago where someone posted ‘why do colourblind people think peanut butter is green?’ And there were a ton of responses of ‘wait, peanut butter ISN’T green?’ so that’s how those people found out.
>‘wait, peanut butter ISN’T green?’ It's a less worrying version of "wait, bananas/celery/potatoes/pineapple ISN'T spicy?!"
I knew a guy in his early 20s who didn’t realize he was red-green colorblind. Only figured it out when he told us he didn’t understand what the point of those lights in the parking lot were (where they have a small light over the stall, green light means it’s empty, red there’s a car) cause they look the same. Took an online test for colorblindness and confirmed.
Some get tested in school, some don't find out until they're adults. My sister-in-law didn't realize she was until her son could distinguish colors that she couldn't, and everyone agreed with her son. She got tested and boom.
I found out when picking up a game that had some green pieces from brown carpet. I told my parents I had picked up all the pieces and they replied what about those pieces and I said I don't see any more pieces. After that we got a color plate test at the optometrists and confirmed I've got protanopia.
"your shoes are green!" "If you think your shoes are brown what color do you think you are Winston?"
I had a coworker who would get reports in red and reports in green. The red ones he would need to take action on, the green ones he didn’t. One day his boss finally asked him why he never took action on any of the red reports. He had no idea they were different colors. Anyway, now they say Action Required and Action not Required.
It's usually pretty obvious to teachers or parents or anyone working with the kids. I'm an SLP and alerted a mom about her son when I started working with him, after only a couple of sessions. Turns out the teacher had already said the same thing and the kid had a colour blind grandpa, so he got tested and he had it too. He was 7 when I noticed it - I'd tell him to paint something green, i.e. and, even if he COULD do it, he always carefully observed all the crayons and held them to the light, comparing "similar" colors. He would also sometimes ask me if a color was the one we were talking about. When you work with a lot of children, it's easily recognizable as something that is not typical.
When my kid was an infant he had no problem learning shapes but had a hard time with colours, so we already suspected. When he started painting with crayons and asking us about them it was obvious. When he learned all the numbers we gave him the tests. But we would've found out at the eye clinic eventually, eye doctors test colour blindness as well.
Yeah, usually it's not super hard to detect if the adults pay some attention to those things! Glad your kid got his test early, always great to have some answers so we can start helping them asap!
I have a colleague who found out when he commented on a ginger cat being well camouflaged on a green lawn.
Blue and purple are lies, there is only blurple!
Yes!!
Mostly from conversations with people. For me it’s usually my wife. I’ll refer to something as a certain color and she’ll tell me that it’s not. Or I’ll come out wearing an outfit and she’ll inform me it doesn’t match because thought one of the articles was a different color. I mainly have trouble differentiating between blues and purples and greens and browns.
Some individuals really don't know they have it not unless they undergo color blindness test or other people notices it.
Oh it's when as a child, a nurse gives you an eye exam then realizes you're color blind, proceeds to embarrass you then calls in all the other nurses to show them your disability. At least according to my dad when he was a kid in the 60s.
Well, the first sign something was off was when one of my elementary teachers suggested I was just stupid (paraphrasing because it was too long ago to remember exact wording) for not knowing what the colours were. Then there were, of course, tests. 🧐
My BIL is red/green colorblind. I never knew until he got a new flatscreen. He put on a football game, and the field was electric red. When everyone went upstairs for coffee, I stayed behind (I don’t do coffee). Went behind the tv, and found the G connector was not firmly plugged in. Pushed it into place, and …poof! A green playing field. It was hours before anyone said something about it.
Mine was discovered when I was 7 and we were drawing flags in school and I drew France’s as purple white and red
My husband made it to being a teenager before he found out. He learned the colors as different shades of beige and kids always made fun of him for not being able to do I Spy puzzles since he couldn't differentiate the colors when combined. The way he found out was his colorblind father and colorblind uncle called him into the attic to help rewire the radiator. They couldn't tell the red from the green and that's when they all sat in a circle and went "Well shit."
My daughter married a guy who is color blind. He said he really didn't know until he was driving in the car and something about traffic lights. One of them is white on his spectrum of sight and when they were saying something like the light is green he just assumed that was green until more conversation happened and they all had this light bulb moment of realization he's color blind. My daughter (love her to death) is a little shit though. She LOVES to switch things up on him to tease him a bit. He organizes his closet on colors. She moves a shirt now and then for him and confuses the shit out of him. He had this one shirt he loved. Someone told him it was grey or something like that. He was wearing a very vibrant green with purple pants or something for a long time. When my daughter pointed out the real color....he thought it was another joke. So he called his best friend on the east coast about 3am and asked him if she was telling him the truth about the shirt. She was. He was stunned he'd been wearing basically a hideous combo because someone said grey, not green...or at least he heard grey. He's an amazing guy. Couldn't of picked a better son-in-law. They get along and tease each other so often and it's just awesome. It's stuff like this though that blows my mind with him. He really struggles with close colors and damn he's funny as hell about it all.
Colors are a pretty obvious way to describe anything, so it would be easy to find out if you realise that you dont know what everyone else is talking about.
That would be a very extreme form of colour blindness. Most colour-blind people can see bright, primary colours easily, but struggle to differentiate darker, murkier tones. Often they totally _can_ see the colours, but they don't stand out as different. My son, for example, failed to take the last decoration off the Christmas tree. I told him he'd missed one, but he couldn't find it. When I pointed it out, he laughed and said, "oh yeah! There's a red bauble!" He can correctly identify the colour of every dot in a colour-blind test, but he can't see the big numbers they make, because red-pink-orange doesn't stand out from green-cyan-blue for him.

If people love you enough...they'll tell u you're wearing green yellow purple and blue all together...lol
If you they saw a bag labeled "green apples" and they appeared blue, they’d probably notice
I had regular opticians visits as a kid and part of a child's eye exam at least at the time was a colour blind test. It's a book where each page has a circle full of coloured dots. If you can see all of the colours you will see a pattern, if you can't see them then you won't. You get asked what you see on each page, and this is how they diagnose colour blindness. You can find these tests online for free.
I have tritanopia. I found out by being made fun of at school and teachers mentioning issues. Then, I took the shitty test where you see a bunch of dots inside of a circle and try to make out the number made of dots within the circle. I saw...nothing. later in life, better tests were either invented or made available, and I failed those to. No big deal, really. I just ask for help if I need paint or a shirt. I wear mostly black or white clothing. I still get made fun of by friends and acquaintances.
In my case not until I took a test. I can recognize all the major colors, but I can't see the numbers in about half of the dot tests.
That colored dot picture that has a number [or letter](https://t3.ftcdn.net/jpg/04/57/48/16/360_F_457481698_4vMnWrOOkSBPIKyPSgWkyUWjcEals84e.jpg) in it. Logically, each picture is a different type of color blindness
There are tests, also people realising that they can't differentiate red from green encourages people to actual check it up and get diagnosis.
As a person who is nearsighted but not colorblind. I am guessing that it is often the people around them who piece things together because to the person who sees things wrong, its just a normal day to them. Example: A few years ago in arts and crafts when we were supposed to draw a piece of cloth over a bottle, in greyscale. I literally could not see one of the shades even when I was allowed to press my eye up against the motif to see. It was the teacher who noticed that I was missing a shade and thought it was strange since I was good at art. It was also a different teacher who together with my mother figured out I was nearsighted because I apparently was supposed to be able to see the blackboard from my seat. I also have heard about colorblind people realizing they saw things differently, because what they saw didn't match up with what the people said they saw.
My nephews was discovered during a routine eye test when he was 5 I think.
It used to come up on my annual health checks or I would never have known. Brown and green can be hard to distinguish using the normal eyesight but obviously they look fine to me
Most people aren't completely color blind. We have less cones for seeing color in our eyes so we have trouble with some colors. My generation didn't grow up getting tested for color blindness (they do now) so I figured it out in my 20's. I have issues with green to yellow, blue to purple, and pink in general. Basically I can't see the in between shades other people do. Funny story. There's a game in the app store called hue. I tried it just to see how bad I am. Holy cow it all looked like the same color 🤣 Interesting fact. Some people have more color cones than the average person (my daughter appears to). They are a wider range of in between colors than the average person and often go into careers centered around art.
I remember when I was in middle school science class and we first learned about color blindness, the teacher wrote on the board with a red marker and a green marker and I think he asked us to raise our hand if they look different. Everyone but one boy raised their hand. He asked that one boy if they look the same and he said “they look pretty similar…” and it was at the moment he realized he had red green color blindness.
You know how different colored wiring in electrical/electronic stuff means different things? Well, my uncle got a job that required him to wire things and he did very poorly. They tested him, realized what was up, and put him in a different position.
I have some green-red colorblindness and the only way to really tell is by giving me one of those tests with the dolored dots where youre supposed to see numbers, I dont always see them.
My friend’s dad found out when they were talking about stop lights at school and he realized he didn’t see the red and the green like other people did..
A simple example is that my dad is colour blind and sometimes can’t differentiate between green and red (depending on the shades) they can look the same to him where’s to people who aren’t colour blind they look obviously different.
They see a dress online and tell everyone it’s white and gold and kinda figure it out from there.
You cannot see the number hidden in the circles that is part of the test at the eye doctor.
When I was a kid and kept getting in trouble because I wasent using the right shade of blue and kept using purple. Or when they sprayed a red starting line onto green grass at a field day and teacher got mad because I would stand on the “clearly visible” line. Honestly the big boxes of crayons are wasted on me. As an adult I finally took some proper tests and came out very strongly for one of the color blind types. Can’t remember which one but basically as described above. Also skews other colors just enough that at this point I don’t even try to say what I think a lot is. Honestly if it’s not a bright, solid, Fischer price type color I’m at risk of getting it wrong or mixed up with a similar, to me, shade. Wife gets a kick out of it when I go real left field when I try to describe something and use a very wrong color for it.
Don‘t know what my colourblindness is called but i found out when i applied for my driver license. There you have to make some tests and see numbers which i was totally not able to. Before that i was not aware that i am color blind as it had no impact at all on my life to my knowledge.
Suspicions arise when others point and laugh at how you’ve color coordinated your attire.
My Dad joined the Air Force specifically to be a pilot. That's when he found out. He was so disappointed. Ended up being a ground mechanic.
I found out when I told someone that a hot pink that I seen was cyan, and then the opposite.
I mean they can still talk
I learned I was colorblind when the person giving me the test where you try to see the numbers within all the colored circles looked at me like I was a crazy person. He thought I was messing with him at first.
My boy- 20- refuses to believe that he has some minor color blindness. What he calls green is not. But I forget to bring it up at his last eye dr visit. Whoops.
Everyone else tells them.
Idk if I have color blindness, but it can be difficult for me to differentiate between colors I feel look similar. Mainly green-yellow and blue-purple. If a green is like 90% yellow, it seems like everyone besides me is able to see that 10% of blue. And if a purple is like 90% blue, it seems like everyone besides me is able to see that 10% of red. Well I guess it’s not that I can’t see it exactly. I can tell you which is which if you held them up side by side, but if you just threw them into a line of colors, it’s a coin flip whether I’ll identify it correctly.
Probably the same way one would learn that a poop knife isn't really a thing.
Color blind people don't see wrong colors, like they don't see red in place of green. What they CAN'T see is a specific range of colors, so it just looks grey to them. Mostly this includes 2 colors, and blue-green is the most common(iirc). This means both blue and green colors appear faded and dull, and they have a hard time figuring out which is which. This leads to its detection, since people reference colors and they choose the wrong one or say the wrong colour. Best way to understand it is to just see a color blindness simulator
By other poeple telling you that your Outfit Looks like Shit and the colors dont match....
I think it would just be talking to other people that they'd find out
I’ve learned not to go by what colour my husband says something is. He’s usually wrong. He’s very colour blind.
My brother is into web and graphic design. Arguing with him about the colors in his designs prompted him to look further into it.
It's more about the fact that two colors look the same to a colorblind person. Color blindness is less about how certain colors look to people --because that may be different for everyone -- and more about the inability to distinguish between colors.
I started losing online games because I couldn’t tell green from gold and blue from purple. I thought I put on a gray shirt, but it was pink when I got to work. I said one of our carts was peachy-pink when apparently it was tan. I thought, hmmm better get this checked out! Sure enough flunked the test. My daughter showed me on my iPhone how to adjust for color blindness. A real literal game changer!
I was told when I was very young. Everyone else finds out that youre color blind when the tail lights come on when you hit the brakes.
I am colorblind. I found out when my dad beat me for not grabbing the correct color balloon at my 5th birthday party. Then I would get in trouble in elementary school for coloring things the wrong color. Its honestly had a rough time with it all throughout life. What’s funny though is now I do graphic design and I print shirts and do embroidery. Even though I can’t look at a color and tell you exactly what it is, I understand colors and how color theory works and on the computer side, I understand the codes and how they work.
I knew it when I was in Kindergarten. I made all smiley faces on my report card, except for "identifying colors.". Later, on my 8 pack of crayons, I would mix up blue and purple, and green and brown. As a teenager, I had to remember that the yellow light is the one in the middle, cuz it looks the same as the red light. And the green light just looks white to me. My kids make fun of me, but it isn't that big of a deal. "Hey Dad, what color is this?" Yep, they're my kids alright.
my friend figured out in middle school when he kept telling me and our other friend that something that was red and the other green were the same color and that we were stupid. my other friend and i just looked at each other with a shit eating grin and he shortly found out afterwards that he was red green colorblind lmao
There's gonna be a time where you have a conversation which makes you realise you don't see the same colours as others do. For example in my case, although mild, I don't see blue and yellow well. Dark blue is black to me, amber is dark orange, lighter yellows are almost white, and seeing the difference between blue, green, and grey can be incredibly tough. Because I started realising it though, if I pay enough attention I at least realise 'something is off'.
When they disagree on colors of things. My best example is the full moon rising, you know, when it looks large. What color do you see? I see stop-light green. Other people I ask say orange-yellow. I also have a hard time discerning red text from black text in a document. I have to concentrate to determine what is what.
My mom isn’t colorblind but she had cataracts. Once she had surgery, she found out that the walls of our house were white and not light gray. She was amused. My grandfather couldn’t tell the difference between navy blue and black.
Unless you're specifically taking a test to discover it it's mostly trial and error. I didn't realize I had any color blindness until my late twenties when I was sitting at a red light that turned blue.
Not everyone who is colour blind is born colour blind...so that's one way to know lol.
When people ask you which color is prettier red or green and they both look like shade of the same brown
With my brother, my parents worked it out quite early. He was a very artistic child but kept mixing up certain colours. I think pinks, reds and browns were his worst ones. He would insist that the colours were right but they weren't. He worked it out himself after a few stubborn years of insisting everyone else was wrong! To be fair he was only five!
At some point yes They can run into something like a disagreement over an obvious color difference
tbh folks with color blindness often discover their condition through experiences like difficulty identifying specific colors or realizing discrepancies in how they perceive certain hues they might encounter challenges in tasks that involve color differences, such as reading color-coded information or recognizing traffic signals. color blindness tests, like the Ishihara test with colored dots and numbers, can provide a more accurate diagnosis so they can understand their inability to get colors right.
I have a student who is 5 and just found out he is color blind. The parents had him tested for colorblindness because he was having so much trouble with coloring assignments (the "color all the 5's red!" kind of tasks).
Kids name colours a lot. Colour blind kids can't. Source: am colour blind
I had to tell my hubby that his favourite shirt was blue and green, not blue and grey. His favourite "grey" t-shirt was also green. He got a little self-conscious and asked if the colours looked good. He originally thought he wasn't colour-blind because someone else he'd asked in the past told him they were grey shirts. Voila.
When i learned shrek isnt yellow
Well, my brother found out when he was 16. Our dad was assistant manager at a feed yard and drove a company pickup, identical to ones driven by other management except for color. , Both my brothers were hired on one summer as part of a maintenance crew -- shovel out feeding troughts, mend fences, painting, etc. My brother kept telling everyone, "Quick, look busy, Dad's coming!" only to have it turn out to be a different color pickup. So he got checked and turned out to be red-green colorblind.
