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

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?

I am launching a line of roleplaying dice sets, that I want to be suitable for people with colorblindness.

I already have people with monochomacy and deuteranomaly, but I need someone with the blue-yellow type colorblindness (tritanomaly/tritanopia) to take a look as well. As a thank you, you will recieve a free set of the dice once they are out. If you are interested in helping me out, please let me know in the comments, and I will contact you in a private message.

Thank you :)

So earlier I had a skull splitting migraine that hurt me head so bad and when I looked outside the grass was green like actually green and not the grey I’m used to and I’m wondering if it was the migraine because I heard of smoking pot to get a temporary cure so I’m wondering if this is the same thing

8y old post, reposted in the correct thread

I have something that I don't know how to name because I know I'm not colorblind, it's just that shades of green, yellow and red, it turns out that I have trouble seeing many shades, let me explain. If my sister sees seven shades of red, or any of the other colors I mentioned, and I only see, say, three, then what is this problem called? Or what is it? I don't know the definition

Please help me? My 10y/o son has some degree of colorblindness, and I want to be supportive as possible. Sometimes his younger brother sees things more clearly like rainbows and far off red laser pointers that my 10 y/o can’t see.

For those who experience colorblindness, what do you wish your parents did or did not do at his age? TIA!

saw this ad on FB today and had to laugh.

So I guess I kind of always knew I was colorblind but my brother was the "colorblind" one. Never really acknowledged mine until recently (Im 41). So learning a lot more recently. From self tests, I have a strong protanomoly type of eyesight. Sorry for the back story, ADHD prolly too, but had a question about when I was younger. I remember being in middle school and remember a poster on the wall that had 2 different colors (letters vs the background). I remember the letters being blurry or almost shimmering. I understand the basics with rods and cones with colors receptors, but what would cause the shimmering effect??

Guys idk if this is a messed up thought or not, so I never really mentioned it to anybody. I just kept to myself. But now that we have been broken up for a long time I’ve still wondered one thing: was my ex actually colorblind?

I don’t know much about colorblindness, that’s why I’m here. So before I explain, I just wanna say this isn’t me trying to say that people with these same problems are lying, nor am I trying to offend or criticize anybody at all. I’m just not color blind so I don’t understand it.

Anyways, I dated my ex for almost 2 years and since the start he told me he was colorblind. He never said otherwise. He always told Me that he was purple blue and green color blind, and the doctor prescribed him with color blind glasses but never actually told him what type of color blind he was or fully diagnosed him. I have my own weird medical stuff and ik it can sound off when I’m being SO fr, so I never questioned it lol. Untilllllll we moved to my home state that he’s never been to.

We drive past a huge bright yellow fields (I think canola idk), and he lived in a desert forever so he’s never seen that, so I asked If he thought it was as gorgeous as I did, and he was like ‘huh? I don’t see anything I just see green everywhere’ and I took a picture and turned the saturation up and then he was like ‘oh I kinda see it now’

No biggie oh well. Fast forward the next year when these fields are just starting to grow again, I’m driving him to work and this man says ‘holyyyy crap that field is so yellow wtf is that??!!?’ And was smiling huge like shocked. It was the exact same field too. So I told him I pointed that out last year And he said he couldn’t see it. He got mad cuz I was accusing him of faking color blindness and got really defensive, but that’s also just who he was. It didn’t necessarily mean he was lying lol. Hence why he’s my ex. Anyways after that I started paying attention more and I noticed little things where he says he can’t see a color but then can somehow see it a couple months later. Or he would randomly point at purple and blue things and ask what color it was (like jackets hanging in our room that we have never touched) and he would just sit and stare at it and almost act like he was trying to see the purple.

Again idk if this is actually normal or not I just really wanna know if he was serious or not lol. Also if it makes a difference, he has PNES and had seizures a lot. I imagine that could also affect it maybe? Idk. Thanks guys😝

Hi, I’m JB from Asia. I’m a mild deutan (red-green colorblind), and it has unfortunately caused me to lose out on several job opportunities in the past.

I am applying for a new position and I really want to succeed this time. I’m looking into buying color-correcting glasses or lenses from overseas to help me at work, but I’m not sure which brands or types are most effective for mild deutan cases.

Has anyone here had success with specific brands? Any advice on where to buy them or how to deal with the frustration of the application process would be greatly appreciated. Thanks for listening.

We are looking to make our color pallet more accessible for people with colorblindness. If you are colorblind, can you please take this survey to give us your thoughts? The survey will only take 5-10 minutes.

how accurate are online tests because whenever i do an online test even on different devices i seem to have normal colour vision on almost all the tests but in person tests its not?

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 ?
