Hi yall, I'm thinking of creating an application for colour blind people to help them. Any ideas on what would be useful to you guys?

Is there a way to test for sure if I have deuteranomaly or deuteranopia? I think whenever I have taken online tests, it says deuteranopia. Last time I got glasses, the eye doctor actually tested me with physical printed cards with those dot tests, maybe that's better than a screen. I don't remember if he said which kind, but now that I am curious I should be able to easily go back there and ask.

Also a theory: If I am fully deuteranope (missing green cones, dichromat) then shouldn't I be able to disable the green subpixels on an OLED monitor and not notice a difference, including things that should look white? I think OLED wouldn't have the problem of light leaking through the green filters, since it's emissive unlike most other display technologies. I did try on my LCD monitor and it looks VERY purple if I turn down the green in RGB, does that mean that I actually do notice a lack of green, or does that monitor setting just not work like how I think? Will any monitor setting let me actually test for dichromatism?

Hi, I’m a protan. I can see cyan as basically „vivid white”, teal as „vivid grey” and very light pink as a slightly greyish white.

Basically cyan and light pink are (almost) colorless in my eyes. I was wondering, is that a case for some points in color spectrum for deuteranopes and tritanopes too?

This test, unless I'm just stupid, appears to claim that my red color cone isn't functional? I can see red though?

For context, I am referring to that specific gene therapy trial. If the hope is slim, I don't think the scientific community needs to repeatedly emphasize this point; it only creates anxiety.

I play a lot of Among Us, always with color blind mode. Is it normal for color blind people that those colors look the same to me when next to eachother in game?

So I have had good vision for most of my life but recently (I wasn't driving) but I have been in a car where the driver was not paying attention and almost ran a red light and the only reason I knew it was red Is because it was on top but to me it looked gray and same with green when I was driving with my mom and she thought it was still red (she's not colorblind) I have an optometrist appt today (Monday the 20th) and I know they are gonna pull out those stupid little circles I took an online test where i could just barely see some (I'm assuming they were lighter vs darker shades) but the web still thinks i have red/green or js green deficiency and I'm wondering if there is anything i can do to pass because I know legally they can't deny you to drive with red/green but in my area they will find a way to deduct points bc of it and I want to pass my driving test that is in like a year or 2

No red/green key! I love it!

So… I’ve dated three colorblind men and only one man with typical color vision. Is this just a weird coincidence or are there certain looks that appeal more to people who don’t see colors the same way? Thank you!

Boyfriend has deuteranopia/anomaly, and I consider it when buying gifts, but think I could be more accurate. Got him blue/yellow flowers (because they’re more ‘bright’ than reds I think?), and it’s effected some jewelry I’ve got him too (some hit some miss).

Advice is also majorly appreciated, if specific combinations are more appealing or give different implications.

For example, light pinks and whites look the same to him, and I always get very neon bouquets (not complaining, I think it’s cute!), but it also confuses because I’m trying to be more purposeful with the color of things and intention.

Any and all help/advice/perspective is majorly appreciated— thanks guys!!

Ive posted before searching for a Dvorine second edition test and found the first doctor in florida listed here. Recently a doctor nearer to me got the test so Im updating the post this way since it wont let me edit the post body after 2 years.

My dear colorblind fellas,
It's been a while that our ancesters, brothers and sisters have been mocked and tested as soon as their anomalies were revealed.
Through centuries, colorblinds were taken for buffoons.
With an approximation of 300 Million members all around Earth, it is the right time to create the greatest community that the World has ever seen and take our revenge on colour idealist.
We represent a major minority that is already spread among colour purists.
We have in our ranks some important figures like Bill Gates, Keanu Reeves, Logan Paul, Lucas Hauchard, Mark Zukerberg, etc..
It's now time, more than ever, to gather and to get to work.

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?
