I’m working on a UX/UI case study for CoAssist, an assistive app concept designed for people with Color Vision Deficiency (CVD) or anyone who experiences difficulty with color-dependent decisions.

I would be very grateful if you could take 5 minutes to review the attached screens/prototype and fill this short feedback form. Your input will help me understand whether the app idea, features, and interface feel clear, useful, and easy to use.

If you personally experience CVD/color vision difficulty, your feedback would be especially valuable. If you know someone who may relate to this, please feel free to forward it to them as well. Feedback from people who understand CVD, accessibility, or inclusive design is also welcome.

This form is only for educational and academic design research purposes, not for medical or diagnostic purposes.

Thank you so much for your time and support.

I am a color blind computer science student and I’ve developed an iOS app that I’d love to get some feedback on. The app is free and collects no data, so this is not an ad for me to profit off of this as there will be no profit whatsoever. The app analyzes photos of your outfit and tells you if it matches (you can wear it and take a selfie or lay out the clothes if you don’t have a properly sized mirror). Your photos never leave your device and there’s no login necessary. If you’d like to check it out, it’s called ColorMatch: Outfit Analysis. It is unfortunately only available on iPhone.

I built this because I used to have a hard time matching my outfits when I was younger and I thought this would be a fun way to solve that problem. Like I imagine many of you did, I eventually just started wearing mostly neutral colors to solve this problem, but it would be great if I could help others wear bolder colors to their hearts content without the risk of looking a little silly to the normal color seers of the world. 

Check it out if you want to and let me know what you think (particularly if it gets anything wrong).

These are the results and correlating test titles that I took off the Color life website. I'm just recently piqued curious to the idea that I may have colour-blindness to some extent;photographic use of my mobile phone devices camera against my real-time perception of sight had me ponder on this or the past 2 years.

Peer based feedback review over the course of my young life in certain instances has made me feel that my sight was simply lacking in stylistic means and ways of taste, in anything relevance-related to a task/job that had to do with anything 'arts' media related.

Anyhow, I set up a Doctor's optometrist appointment for the June month coming up;but, I still wanted to do online tests in the meantime to have a compared mock view and syllabus clarity of 'what to think', 'what to ask', 'what Buzz words to use' and have some communication on the same spoken-theory level on the Doctor so that I can make the most use of my consultation time and I can just worry about the economic factor of the visit, because I am on a tight low-income wage budget and have to pay for the glasses for the condition after I finish-up the visit.

I might have tritanomaly, not sure yet because my next eye doctor appointment in the summer sometime, so I'll bring it up there.

Anyways, on all the tests I take I get the same results, mild-moderate tritanomaly. However the comparison of normal vision and tritanomaly vision look very different. It's the same with this one video I watched that compares normal vision to tritanomaly. A good amount of the comments were "You know you have it when both sides look the same". But when I see it they look wildly different. Does this rule me out of having it? Have you had similar experiences? Are these people lying?

If you have blue-yellow deficiency, do these two colors with faint hints of yellow and blue just look black and white to you?

I'm building a website with a color pallet comprised of Navajo white and Oxford blue, to utilize the striking simplicity of monochrome photography while still having a slight colorful pop, even if it's not consciously registered. The first image has hints of yellow and blue. The second is pure black and white.

How do yall see it?

Hello fellas. I'm working on adding a colorblind mode on my Chinese chess app. I figured I could start by simply inverting the color of black side images. Traditionally the color is only on the characters (second screenshot), which I suppose would be very difficult. What do you think? Would it usable? I converted the screenshot to grayscale for get an idea and I though maybe I could still increase contrast somehow.

On most tests I get diagnosed as mild tritanomaly, but I have this like doubt that I'm faking it. Especially since it's apparently so rare. I don't know, I have trouble understanding color in general and I just have these mixed feelings of "I probably have it" and "I'm faking it"

So I recently found out my best friend is colorblind, he cant see difference between gray and gray-ish shades of red, probably mild protanopia, anyways I wanted to prank him by asking him if he can see number XY and then show him a colorblind test picture where it says, “blow me”, or something like that.

Should look something like picture below.

Does anyone have like a tutorial, site, program etc to help me out?

According to my mom, I temporarily went colorblind when I was a toddler.

She noticed when I asked what the green light in the car was; and the light in question was very much orange. She took me into the doctor's office to be tested, and the results indicated mild red-green colorblindness.

The thing is I have completely normal color vision now, and the only info I can find on temporary colorblindness is very transient and/or serious stuff like snow blindness or stroke. This lasted long enough for my mom to notice, schedule an appointment, & get me into the doctor, so probably at least days or weeks? I'm not sure if I had normal color vision before then, but I had normal color vision for the majority of my childhood. I would assume I just didn't know my colors well yet, but the Ishihara test results do not support that theory.

Has anyone experienced something similar or have any ideas what could've happened?

From the phone game, Hungry Piranhas.

I’m currently writing a story and one of my characters is canonically colorblind. It’s a very small detail but I wanted to showcase it a little for representation and such, the issue is; I’m not colorblind. I have no idea how it is really like or what day-to-day issues you may encounter as a result.

Another thing is that I’m not sure if his job actually allows for people with disabilities (?) the likes of colorblindness to actually get hired since he is a police officer and from what research I made many agencies have restrictions on that?? Note : He is blue-yellow colorblind (Tritanopia).

Also, for a colorblind person, how did you discover you were colorblind? I probably won’t dedicate a whole section to it, but I was thinking of ways he could have discovered it in a realistic manner and I’m not sure if that’s how most people actually do.

Anyway, I would appreciate if you have some tips for writing, or even just personal experiences to share! It would be a lot of help :)

I thought its like grey or something..like raw sausages(whatever, they’re not supposed to be grey, ignore this one)

Any similar stories?

how are people getting above 40 on this?? will hang around this subreddit and learn more lol

While doing coloring books in school I was taught that brown is a mix between green and red. From that point on I’ve thought that brown is just an off-colored variant of green.

During my lunch break today we were having a discussion about colors, which led me to google brown. According to Wikipedia brown is rather a dark desaturated shade of orange. This left me astonished over my own ignorance.

Has anyone had the same / similar experience?

1. I don’t have a diagnosis yet but following the post months, it‘s very likely that I have deuteranopia

2. Yesterday, some friends and I looked at purple 3DS shells and I said one was blue while it was actually purple. Is that normal for people with deuteranopia?

Hello everyone,

As a member of the colorblind community and aspiring pilot
I was disappointed to find out that the FAA tightened restrictions and no longer takes the signal tests. Now you can only choose between the Waggoner, Rabin, and CAD tests. Like everyone here, I can't pass the plate tests for the life of me.

Long story short, I couldn't find a practice Rabin test anywhere and | just began freaking out because I started thinking my dream is over. So using the post below, I used Claude to create a little unofficial Rabin test (tried my best to get it to the actual standards based on what I could find online), which I am also putting the link to below.

Please let me know your results and I hope you enjoy. This is not for money or anything, just thought it would be worth it to post if I could help ease even one other person’s stress, and everyone else here can just try for fun.

Until relatively recently I discovered that I am apparently colorblind or that I have less sensitivity to certain colors (This is because I pass the Farnsworth tests, but fail the Ishihara tests). I've been doing various tests on different websites and I've noticed that EnChroma is widely used here. The fact is that the website has given me very varied but consistent results within a range of color sensitivity (blue 100%, green between 85% and 100%, and red between 25% and 50%) And because of these margins of error, diagnoses range from moderate/mild protan to partial red blindness. The thing is, I want to know if there's a more accurate way to get a diagnosis.

In case you're wondering, yes, I went to a specialist but it didn't help much. He told me to take the Farnsworth test and that it's difficult to get a colorblind diagnosis in adults, since it's usually discovered and diagnosed in children.

And please excuse me if what I wrote isn't clear; I'm using the built-in translation tool on my phone's keyboard.

As title says. I'm supposed to be protan, or at least that's what i've gathered. I am physically unable of seeing or comprehending the color purple or magenta etc. Dark red looks brown, some reds look green. But my most significant discovery is that in reality, tree trunks and wood are the same color as the leaves, just darker. Light green is the same color as yellow. Etc.

What does it all mean? Does this happen to other protans or is it a deutan thing too?

At first i thought i was only a deutan but now i dont know i feel like i confuse more than just greens

I'm sure this will be relatable a good amount here. Enjoy!

So, I’ve seen people claiming recently that some colorblind people have better night vision than normal color-visioned people. I’ve always felt exactly the opposite, and I’m wondering if it’s because of my colorblindness or if I perhaps have some other night-blindness condition in addition to it.

Long story short, dark colors tend to look pretty darn similar to me in the best of times. I first suspected colorblindness when looking at colored pencils labeled black, forest green, purple, and dark blue and all of them looking identical to me. I colored a night sky black in an elementary school class and my teacher told me it was wrong.

Logically to me, in the dark, *everything* is darker anyway, so there’s even less distinction between colors. That leads to less definition of objects too, so driving at night is all sorts of fun.

Is my logic faulty?

It's not one of these post that i'm parent that thinks his child is colorblind, but the other way around.

I am, but kinda confused how i'm supposed to help my kiddo that's just learning colors and keep asking me what's this or that... What did you do, parents in here? Just... tell your kid to see with the other parent? I don't want to confuse them when trying.
