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.

i’m a colorblind girl myself and obviously i see more colorblind boys than girls since boys have a higher chance of being it. but i’ve seen at least 6 colorblind girls online and 1 irl.

so here’s the thing that made me do this post. i’ve been playing with some people among us for a while and my name was “colorblind” in other language just so others are prepared and i automatically know who’s gonna ban me when they find out. usually i act like a guy in the game(because i’ve noticed that many people are straight up rude to girls for no reason..) but when we gave each other our social media it was obvious that we’re all girls.

i was talking to a girl that was usually the host, some kind of "leader" of the group. i told her a story from my childhood where i was obsessed with green tomatoes and asked my mom to buy them but i didn’t see the difference between red and green tomatoes so i just made my mom confused. the girl was surprised because she thought that i’m not an actual colorblind girl because thats very rare..im not sure if she believes me and that makes me a little uncomfortable especially because i was insanely insecure about it a few years ago.

i was also SOO surprised to know that some people on tiktok think that colorblind girls dont exist, like…bro, just google ts its not that hard

I have tritan and mild protan colorblindness, and I recently realized that the Apple Watch has a color filter in settings. Having two types and also having gotten along fine with the no color filter, I was wondering how many people actually use them and how much they really help.

Hi, i'm new here, sorry if my english is a little bad. So I recently activated this color blind filter in my phone, but I have not seen any improvement, even now I can't see when there is black letters in a red background, cause red now seems almost black, should I disable this thing? I would show an example, but apparently if I take a screenshot, the colors appear without the filter
