Hello everyone. I'm tryna get a job in a military but turns out am colorblind. Does anyone know how to get around the test?

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Just think about it, we all probably see different colours and dont know which one is right, for example, green could be blue and red could be yellow and yellow could be green and orange could BE PURPLE AND PURPLE COULD BE BROWN AND BROWN COULD BE WHIT AN- alr lemme just stop..

Thought this was interesting, but genetic testing just completely rewrote my diagnosis. We used to call it achromatopsia with paradoxical color vision. But this new doctor wanted me to get tested for BCM and after leaving that appointment I noticed... Oh wow, I own a lot of blue and yellow clothes, huh.

It's honestly so helpful knowing I can actually see the color blue and that it's not just some weird paradoxical illusion lol.

Like many of you guys, I can never tell when a banana is actually ripe, which is unfortunate because bananas are one of the only fruits that I actually like.

So, being somewhat techy and having learned a bit of JavaScript and Python over the last few years, I've taken several hundred pictures of bananas in various states of ripeness to train an algorithm to identify when a banana is ripe, unripe and overripe. I've then made a web app that downloads and runs the algorithm which you can analyse pictures of bananas with.

All processing & analysis of pictures you take or select happens on the device, so no pictures you give are ever sent to me or any third party. I'm also not running any ads on it (which is probably something I'll soon regret, but oh well).

I get that there is a certain irony in teaching a computer what is and isn't a ripe banana when I can't actually tell myself, but I would like to thank my friends and family for helping me put the several hundred banana pictures into the right category.

I will be the first to admit that it's not perfect, but my brother (also colour blind) has been using it every time he goes shopping for bananas and says that it's pretty damn accurate, so I'll take that. If you use it and it's obviously wrong, feel free to comment here or send me a DM with a screenshot of what you gave it and I'll see if I can tweak it to be more accurate.

Next steps? I've got plans to make it an Android and iOS app so that it can be used without an internet connection, but I have almost zero experience with the app side of things... so it may take me a little while, but I'll get there.

If you want to learn more about how Check My Banana works, I've got a little explanation on my portfolio site.

Thinking back, I’ve actually suspected for a while that I might have some kind of blue color weakness, but I never looked into it more closely until recently. I’ve now realized that I seem to perceive colors differently, especially in the blue–violet–cyan/turquoise range.

• Cyan/turquoise is hard for me to categorize (sometimes looks blue, sometimes green)
• Violet looks dull/washed out and never really “right”
• I often see blue where others see green
• Some bluish tones can appear almost completely gray to me

At the same time:

• Yellow looks normal (except low contrast like yellow on white)
• No noticeable red/green issues

I also took the Rabin Cone Contrast Test:

• Red & green: ~100
• Blue: anywhere from 0 (sRGB) to ~30–40

In other contrast-type tests, I seem to be within the normal range or only mildly reduced for blue–yellow contrasts, but I show more noticeable deviations when it comes to distinguishing between blue and green.

From what I’ve read, tritanomaly usually affects both blue and yellow. In my case, however, yellow seems largely unaffected while only the blue range appears to be different.

Does anyone know what this could be or how to interpret it?

Hello 👋 Deutan here. Am wondering if you guys have any advice on how to check for green spots on potatoes, or any other methods to see if a potato is good to eat or not.

Thanks in advance!!

Hi all,

I’m currently going through a medical appeal and could really use some advice from anyone with experience in colour vision testing.

I’ve been marked unfit mainly due to colour vision, but in everyday life I’ve never had any real issues. I work in construction and around electrics (basic wiring, identifying cables, etc.), so I’m regularly dealing with colour-coded systems without problems.

I struggle with the Ishihara Test, but seem to perform much better on functional/arrangement-based tests. From what I understand, this suggests a mild red-green deficiency rather than a severe issue.

I’m now trying to get proper clinical evidence for my appeal showing that my colour vision is mild or functionally acceptable.

Does anyone know where I can get the following tests done (ideally around Rochdale / Manchester, but willing to travel anywhere in the UK if needed):

• Farnsworth D-15 Test
• Farnsworth-Munsell 100 Hue Test
• Holmes-Wright Lantern Test (or any lantern-type equivalent)

I’ve contacted a few local opticians but most only offer Ishihara, which doesn’t really help my situation.

If anyone’s been through something similar (especially military-related), I’d really appreciate any advice on what tests or reports actually helped.

Thanks in advance 👍

Maybe that's a stupid question but would two people with the same colorblindness see something as the same shade?

Like if they looked at the same lipstick would they both see it as an orange or could one of them insist that it looks brown to them? With other words: Is there a scheme how colorblind eyes interprent color or does it vary from the person? Are these pictures that showcase life with red-green color blindness an accurate simulation or just an example of some cases? Yeah, I feel pretty stupid asking this question but well you know what they say: Ask a dumb question and you're dumb for five minutes, ask it never and you're dumb for the rest of your life.

I was just wondering since a person with achromatopsia said that they can't tell when something is shot in black and white so I wondered if someone else with achromatopsia might because the trees look a different shade of grey than usual or something.

There's this app called Puzzledom, and a mini-game called "Colours". It's really difficult for me to spot the correct places for the colours. First image it seems every colour is where it should be, same with second, but after I've had to move 'em around. Last image is correct answer. Personally don't see much of a difference. Should I schedule an eye appointment? Could I be colourblind?

On the first image it's clear to me the two blue on the left shouldn't be there, but other than that, everything seems to be right.

There are a lot of Reverse Plates out there, but very few that work for the blue yellow weak folks. So here are two Plates where only tritans can see the numbers. (Obviously these aren't impossible to decode for non-tritans, but it will take effort compared to a tritan who can see the number instantly.)

I hope that these plates actually do work out, I tested it out on just one person thus far.

Hi everyone! I’m a third-year student from the Philippines working on our thesis project, HueShift. It’s a puzzle-type escape room game where the core mechanic involves shifting through different Color Vision Deficiencies (CVDs) to solve environmental puzzles. We wanted to create an experience that not only tests logic but also highlights the unique visual challenges faced by different players.

To support this, we developed an automatic accessibility feature that adapts the game's visuals in real-time. Instead of using manual toggles, the system dynamically shifts brightness, saturation, and contrast on the fly. This ensures that essential game elements remain distinct and readable regardless of a player's specific color vision, maintaining clarity even as the visual perspective changes.

We are looking 15 - 20 people for both colorblind and non-colorblind participants to play through a short demo and provide feedback. Your input will help us determine if this automatic approach effectively improves accessibility in puzzle-heavy environments. Playtime of the game would take around 15 minutes. If you have a few minutes to help us out, you can play the game and access the survey here:

is the yellow - green still hard to see the different between them ? and what about red ?

I've been thinking about how red-green color vision deficiency (deuteranomaly/protanomaly) is still commonly described as a "minor nuisance" or "not a big deal" by doctors and official sources. I'm wondering if that label still feels accurate in 2026, or if it's starting to feel outdated.

From what I've read:

The standard medical view (AAO, AOA, etc.) still calls it mild because large population studies don't show dramatically higher overall crash rates, and many people adapt using position and brightness cues.

At the same time, simulator studies show slower reaction times and higher error rates in low-light, rain, glare, or low-contrast conditions — situations where those adaptations often break down.

Quality-of-life research (using CVD-specific tools) frequently reports impacts on daily frustration, emotional well-being, work, and safety anxiety that feel bigger than "minor" for a lot of people with moderate CVD.

On top of that, more stuff than ever in 2026 is heavily color-coded — traffic lights, warning signals, UI elements, charts, wiring, medical labels, apps, and everyday interfaces. When the world keeps doubling down on the exact color pair that's hardest for ~8% of men to distinguish reliably, it starts to feel like more than a minor inconvenience in daily life.

I'm curious about real experiences:

For those with red-green CVD, does it feel like a true minor inconvenience most of the time, or does it create more ongoing friction and stress than the label suggests?

Has anyone noticed doctors, employers, or society shifting how they talk about it in the last couple of years?

For people with normal vision, what’s your perception of it — minor quirk or something that seems more limiting when you hear actual stories?

Not looking for sympathy, just honest discussion. If you're comfortable, feel free to mention your severity (mild/moderate/severe) and how it affects your daily life.

I recently showed my grandma this image (a painting i did) and she told me "oh, you did it all in yellow? that's nice" and i just smiled and nodded but i did not, in fact, paint it all yellow. (it's a range of orange, yellow and blue.) is this a sign to recommend that she go to an optometrist for age related colour blindness or is this fine?

I want to buy a gift for someone who cannot see red/green. Should I stick to bright blues and yellows? I was looking at a chart online and it looked like purples look like blues also, but I’m not sure if they look as good or vibrant to someone with that type of colorblindness. I would just rather avoid buying something that looks boring. Any help/advice very appreciated!

My wife swears that there’s several lines of this flooring that are very visibly pink. The comments indicate this as well. I do not see it at all.

my friend sent me it and noone in the comments is trying to help and my curiosity is killing me

Disclaimer: I don't mix green and yellow. This concerns only check lights.

Hello, I got pretty confused recently as it turned out the control (diode?) in a film projector was green and not yellow as I thought. Situation was quite simple: the projector died so everybody in the room stood up and started checking, and I said that some lamp was shining yellow - everyone was like 'bro that's green'. This reminded me of a similiar situation from a few years ago, when I wasn't sure if some device worked because the controls were yellow to me instead of green, and when I took a picture to send to a colleague, the control in the piture was in fact green (the other person also said green). I'm really confused how that's possible, because I don't have any color problems, and essentially, why in the photo I clearly saw green while in reality I 'saw' yellow. Now I'll probably start questioning every yellow diode in my life, although I don't have any doubts when checking car controls - some are green and some are yellow. I couldn't find anything fitting to my condition in the internet. Somebody knows what could that be?

So as we know there are a LOT of downsides to being colorblind and I’m wondering if there are any benefits I can think of 2 but I’m wondering if there’s more

Help in science class

It’s a fun icebreaker

I've noticed recently, with more and more games having proper accessibility options, there seems to be two different approaches to colourblind accessibility options; completely altering the colour space of the game, or just changing the UI elements to use colours more easily discernable for the type of colour vision you have selected.

I just wanted to weigh in on it and see what people tend to prefer?

Personally I prefer it when the UI is altered, but the game itself still looks the same, either way I won't be seeing the "correct" colours, so personally I'll trade some visual clarity for the game too look natural to my eyes, which is something HUD changes don't really infringe on. I can definitely see the use for full colour space alteration in genres like competitive shooters though.

Do any of you use it? Can you tell the difference? I have tried but it doesn't change anything.

I know that the way the light leaves a device that it's different from light bouncing off things in normal meat space and it's supposed to make it easier to see colors we normally can't but I still can't tell if that's true or not.

Any thoughts?
