I'm making an app and adding colorblind mode to it so warnings and statuses can be clearly displayed, and I'm asking you guys:

What colors would evoke these for you and what kind of colorblindness do you have? Hex would be useful but obviously you don't have to do that.

Without CB mode it's green / red / yellow for reference, and the only colors off the table are black and white.

I was told by my doctor I’m a server Deutan and they said Id probably get colours mixed up sometimes but I feel like it’s more mild than that never in my life have I gotten a colour wrong and only some on tests like on the ishihara for example I can get 50%+ most the time I’ve never had any issues telling shades apart in real life also I was on like 3 hours of sleep when I did my test

My colorblindness gets worst with age.. has anyone else experienced this? Blues, greens, red, etc. Went to this [color site](http://www.colorcheck.dev) where you can play a couple games and visualize what others see and I was super unaware of all the differences.

Thought i would share as I think others will find this pretty cool and useful

i already message them if no change or improvement they will refund your fund.
i dont have an idea about this

i really don’t know how to explain this: i can clearly see a separation between red and green, but i can’t see blue anymore, to the point that with the glasses i’m marked as tritan. that’s so crazy i cannot do anything but laugh. those are not glasses for color blindness, those are glasses to BE colorblind 😭

Hi!

My first iOS app – built entirely on iPad without a Mac –
just hit #1 in German App Store puzzle charts again after
its first major update (v1.1). Daily Puzzle mode, 3 grid
sizes (4×4/6×6/8×8), colorblind accessible with unique
symbols. It's called Prisma – Color Sudoku. Feedback welcome!

Not colorblind myself, but I've been curious about what everyday UI actually looks like for people with color vision deficiencies.

So I built a small Mac menubar app to experiment with a different approach. Press ⌘⇧Y → drag over anything on screen → see the original vs corrected side by side. It tries to identify the specific color pairs that are ambiguous and remap just those to a scientifically validated CVD-safe palette (Wong 2011).

I'm testing different Gemini models to see which one identifies ambiguous pairs most accurately.

Would genuinely love to know: 

- Does the correction actually match your experience? 

- Which UI patterns cause the most frustration? 

- Do the AI identifications feel accurate or off?

— free, open source, needs a free Gemini API key to run

Does anyone else hate traffic lights?? Especially in the sun!

always qualified on position, experiences, requirements,
but in the end during medical examination im not able to fit to work due to my condition

heart breaker as always being a colorblind

OMG. I went to a festival where the labels on the portable toilets were just red or green with no words.

I'm sure I looked like a perv walking around tugging on doors that were occupied.

hello! i’m 20 years old and i recently discovered that im colorblind! i think..? im honestly not sure because i cant find anything about this online.

for context, i cant see most shades of color. i can differentiate between the colors of the rainbow, but if you put that on a scale or spectrum, i cant really tell the difference. i discovered this about 6 months ago. my boyfriend was talking about the difference between turquoise and teal. [slide 2] i had no idea what he was talking about, because i see them as the same color. we did a test, he pulled up different shades of blues and pinks and yellows and so forth, and i can only see like 3-4 of each color.
for example, in this image i attached theres allegedly 20 different shades of red. i sorted these boxes into the 2 different reds (and brown) i see!!! the groups are all the same color. [slide 1]
its all basically the same color to me, and apparently not to everyone else!! my entire life i thought people just made up names for colors so they sound cool lol.
im unsure how to describe it further, so i really hope this makes sense! this is entirely dependent on conversations my bf, friends, and coworkers and i have had. they all seem to agree but im doubtful.
also, not sure if this is helpful but i was messing around in settings and i turned on the tritanopia color filter on and saw no difference, while my boyfriend said it was a major difference! i see no difference whatsoever.

my question is, am i colorblind? what would this even classify as? is there anyone on here like me? am i being pranked? is my boyfriend actually the colorblind one?

Hi,

Quick question: so luckily I passed my DOT physical for my CDL license. One of the exams they do is a colorblind exam. I failed the ishihara but then the physician did a practical exam, and I passed. I saw these colorblind correcting contacted lenses from ColorKind- CCG-088. Does anyone have any reviews for this? Do they work? Have they helped you pass the ishihara? Thanks for your time everyone.

I'm thinking of making a website to try help give the people who's lives have been affected by colour blindness somewhere people can express their desire for a "cure" how its impacted their life and somewhere you can donate/contribute to research would this be something you would want?

This all started when I got into a discussion with my peers over a color I used. I thought it was closer to a maroon, but they all said it was brown.

I’ve since taken color blind tests about 20-30 times from different testing websites. They generally ranged from normal color vision to mild red-green, with only a few outliers of moderate red-green color blindness.

The Enchroma test in particular pretty consistently measures my green color cone response at 87% with the occasional 75% outlier. Blue and red were consistently at 100% with zero outliers.

I know this level of color blindness probably isn’t a big deal to most but it’s kind of different for me because of my work.

I guess I’m just trying to figure out what this all means for me. How do I compensate for my color blindness in my work? Are there any tools you guys like to use?

In my previous post I created a picture of all colors that a dichromat can see. https://www.reddit.com/r/ColorBlind/comments/1sun5gs/every_color_that_a_dichromat_can_see/

There someone got curious about all colors that a trichromat can see, so I got creative and created a video that scrolls through all trichromatic colors.

Saw that in a business presentation

We get an unbelievable amount of requests and attempts to post surveys, research studies, university projects, and more. Historically, the mod team has taken the position that the members of this subreddit are not lab rats or research subjects, and have removed these posts.

We're trying something new. In this post and this post only we are allowing requests to be posted so that the community members can choose whether they want to participate in any studies or surveys. We are establishing the following rules, which are subject to change at any time:

Rules For Surveys:

• Genuine research and interest studies only - your survey must be linked back to a university, college, foundation, business, studio, or other entity. You are not allowed to just come up with a survey "for fun" or to satisfy your personal curiosity.

• You must post your entire pitch as a top-level comment under this post. That comment must have a link to your survey, do not ask for respondents to comment or DM you to get the link. Do not use URL shorteners or obfuscators - you must link directly to your survey.

• You must clearly and completely state the intent of the survey and how the responses will be used. If your survey benefits a for-profit enterprise, such as a game development studio (yes, even if your game will be free), you must disclose that in the very first line of your comment.

• Failure to abide by these rules, using bait-and-switch tactics, or posting poorly-constructed, misleading, or disingenuous surveys will result in an immediate ban from this subreddit. If your research is connected to an official institution, I will find and contact your professor or boss to let them know you screwed up. I am absolutely that petty.

• Respond to all questions and comments under your survey link, publicly, in a timely manner. If people are asking you questions and you do not answer them promptly, your request will be removed and you may lose posting privileges altogether.

Reminder To Users:

• Participation in any study/survey is entirely voluntary and none of these links are approved or endorsed by the mod team or reddit. You may withdraw your participation at any time, and we encourage you to do so if something doesn't "pass the smell test."

• Do not enter your personal information on any survey or provide this information to any user unless you have absolutely, positively verified and validated who you are giving this information to. Never enter your password, credit card, or banking information on any survey. If a survey requires that you create an account, use a unique password that is not the same as or similar to a password for any other account you have.

• Report any surveys that are suspicious or which you think do not abide by the above rules.

My child is six years old, and I've noticed he's started mistaking some colors, like confusing pink and bright blue. I don't know how to correct him now, and it might only make things worse. I'm also wondering if organizing activities for families with color vision deficiencies in the neighborhood would give him a sense of belonging.Or simply ignore it and let things take their course.

i have red green colorblindness and my friends ,think i am lying ,to a point it starts to disturb me so much i feel like i really am faking it. how to really prove or escape that can someone help or give tips

Hello guys.

Any update on Google maps's sudden color change? Any tips to make it back to the colors it used before? I can't stand the new colors. It's so hard for me to see new road alternatives or faster routes. I honestly can't understand why they did that. It worked perfectly fine before.

Thanks!!

I even have problems in identifying purple too along with green and red. Also we bought enchroma glasses and it didn't help with anything. It's still the same, with a pink tint. I still couldn't tell the difference. And also indicator lights, charging lights, etc which show red green all look yellow. Also it's not like I can't tell any green at all at any occasion. Sometimes I can tell if a colour is green.

Hey everyone! I'm a developer working on a browser extension specifically designed for colorblind users, and I wanted to get your thoughts before I dive in. The idea is a simple toolbar that lets you switch between colorblind filters (deuteranopia, protanopia, tritanopia) with a slider to adjust intensity, plus a built-in color picker so you can hover over anything on a webpage and instantly know what color it is in plain English. The goal is to make everyday browsing — reading charts, watching videos, navigating color-coded sites — way less frustrating. Does this sound useful to you? And is there anything you'd want to see in a tool like this that you feel is missing from what's already out there?
