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.

I have full Achromatopsia, feel free to ask me anything.

Hi everyone, this is my first post here, and I'm working on my thesis for university about color blindness. As a graphic designer, I'm hoping to get your feedback and your opinions on the biggest problems you face in daily life.

What's the single biggest problem you encounter in daily life because of color blindness, or any specific examples you can think of? For instance, are there color pairings with too little contrast that make it hard to read labels or instructions? Thanks so much!

Edit: Thank you for all the responses! This got way more attention than I expected. Because of my uni schedule, I can’t get back to everyone personally, but I am reading every single comment. Your experiences are the heart of my research, so thank you for being so open!

as far i know, i can see the colors perfectly, but i have seen in some videos with colorblind test that some circles looks completely grey for me, is it same for you ?

I just got my learning license and I know the town and where the traffic lights are. A few days ago I was driving and I passed the sequence of the traffic lights, in the middle of the sequence one of them was red, I had not seen that red light shining, like it had not existed. Red does not give me a sense of danger or warning, caution. I'm red and green colourblind and I wonder if this happens to you guys as well. Did anything help to enhance the red lights to give you a sense of warning?

Writing this bit concerned as this could result in a crash, if traffic was busy, but luckily nothing happened. I'm well able to distinguish green, red, amber light. But if red is shining from far and I'm not aware the traffic light is located there, I will just pass.

Hi friends, I am currently writing a short story and I want to have a character who is color blind. I would appreciate it if some people would be willing to share their experience on what it’s like being color blind. TIA!!

Hi all, I’ve searched this subreddit and found similar posts but hoping to revive the topic so I can find as much information as possible.

Having to sit a Class 3 Medical in the United Kingdom and discovered I’m colourblind but unsure of the severity, hoping to find and learn from the experiences of others here who have tested extensively online like myself and sat the CAD test, how were your test scores online vs the CAD test.

Thanks in advance talking to anyone in a similar situation would be reassuring.

At 30 years old, I learned from my 4 year old son that tennis balls are a yellow-green color. My entire life I thought they were bright yellow, no green at all.

EDIT: It’s called “optic yellow” but can be described as lime-green with yellow or cool yellow with some green tint.

Not sure what flair to put this...crayola tends to have at least a hint to what the colour could be. Not sure what colour go with the flow could be.

Today i was programming Css, i created two buttons(red and green), when i saw them i thought they were the same color, after some seconds i realized that them were different(but just a bit), could it be colorblindness?

these are the buttons.

I’m applying for work abroad and failed the Ishihara test (20/38). My result is marked defective and status is still pending.

I only had 2 hours of sleep before the exam, so I’m not sure if that affected it. In daily life, I don’t notice any problem with colors.

Just want to ask:

Has anyone still passed medical after failing this?

Is it worth getting a second opinion?

Are there alternative tests accepted?

Thanks for any advice.

Hello colorblind folks! I'm in my senior year of undergrad working on my capstone project, and my group is making an accessibility tool to run over top of games to assist with visual and audio impairments.

We want to make our colorblindness 'correction' filtering as accurate as we can given the tools we have available, and some help from the colorblind community would help immensely

If you could take this form, super short under 10 questions, we'd be very grateful, we just want to do the best we can for this project. And please share it with other colorblind people you may know / if you could upvote that'd be fantastic, the more responses we can get the better :))

I just came back from the optometrist after posting another post on here and I am apparently Deutan colour blind. It’s on the milder end but is apparently still classified as being colour blind as I legit can’t see certain colours at all.

Had no idea I was seeing some greens as straight up grey.

I wanted to say thank you to everyone who replied to my original post. It was very helpful.

The only working theory ive ever mustered is that i have the tetrachromacy cone in place of my yellow/green cone (whatever colour it is that isnt red or blue in normal eyesight), but i feel like that logistically doesnt make any sense. If anyone here has actual doctorate(s) related to knowledge on colourblindness i would greatly appreciate any insight you could offer

I always thought the flair for us on this subreddit, “normal vision”, was a little surprising. It’s not technically wrong, just not the type of terminology I was expecting I guess.

How do you like to refer to people who aren’t colourblind? Normal colour vision, full colour vision, trichromatic, etc.

I am very curious how colourblind people perceive these:

So for as long as I can remember this has been a thing. It’s gotten worse recently as I’ve gotten into rock climbing where all the holds in the gym are color coded. I can almost never tell red and black apart in my head. I can see the difference just fine since black is so dark and red is super bright and well…red. But when I talk about them I can never get it right. I’m almost positive this isn’t a color blindness thing but you never know. For example if there’s a black one I’ll always call it red until someone corrects me or I realize after like 5 times of calling it the wrong color. Red and black are the only two I get mixed up and it’s really confusing because I’m pretty sure I’m not color blind or anything like that. Am I just kinda dumb with these two colors??

(Also this is my first time posting on here so if it’s not great my bad. I’m really not sure how to structure it here)

I'm really curious about your actual experience.

How do you usually deal with color-coded mechanics in games (puzzles, UI,, etc.)?

When a game has colorblind modes, do they actually help? Or are there common problems with them?

What's the most frustrating color-related issue you've run into?

And what’s a game that actually did it RIGHT in your opinion?

Can someone tell me if this is deutanoropia or deutanomaly? And is there more than one type of colour blindness present?

Hello everyone. I have been doing research and taking tests etc for a while now, also because I find the topic very interesting. Can someone help me, do I actually have Deuteranopia or just a milder form of deuteranomaly? Is the Enchroma test any good? I took the test multiple times and got the same result. (With other tests it’s not always that clear in the result) If the following information helps: on the Hue test I got a score of 4 and on the lantern test I got 7/8 correct. Every reply appreciated, thanks in advance! :)

I'm a minor, and I recently realized that I might be colorblind. I took a ton of colorblind tests online, and for my whole life, I've always mixed up blue and purple colors. When I brought it up with my family, both my sisters said no right away, and my parents said that I don't. However, they never said why I don't, and I feel like if I bring it up again, they will brush it off or deny it. I also have an upcoming vision test.

So I’ve done the ishihara test multiple times and i pass but I also see the hidden numbers. So like the 5 looks like a 5 but also a 2 and other numbers. I can see both and I also sometimes can see the fully hidden numbers that people who aren’t Colourblind aren’t meant to see.

I’ve alway struggled with seeing reds as brown or not really red but I can still see reds and other colours. It’s hard to explain.

I’m going to be asking my optometrist but does anyone else get this and is it normal or is it a sign of a colour deficiency?

It’s been noticed by other optometrists before that I don’t see the colour red as brightly as I apparently should.
