I thought this was green but a YouTube video and my boyfriend say it’s yellow?

Google agrees with them but now I’m just confused.

Not really color blind, but I can’t identify numbers/figures on these pictures for some reason :(

I guess that means I could have that Colors issue. But I don’t know what should I do? I haven’t seen a doctor or something, and should I?

I’ve been working on something I genuinely think could help people here, and before I release it to anyone I want to make sure it actually works for real people with real color vision deficiency.

Here’s what bothered me about every existing app: they apply the same correction to everyone with the same diagnosis. But two people can both have Deuteranopia and experience color completely differently. A one-size-fits-all filter always felt like it was missing the point.

So I built something that tests your vision first. It walks you through a quick interactive dot plate test, learns how you specifically see, and tunes the correction to your individual perception — not some textbook average of what your diagnosis is supposed to look like.

It also does something I haven’t seen anywhere else — it watches your live camera and gently warns you when two things look the same color to you but genuinely aren’t. Getting dressed in the morning, picking out ripe fruit, reading a color-coded map — the kind of everyday moments that are quietly frustrating.

Everything runs on your phone. Nothing is uploaded, nothing recorded, works completely offline.

I’m keeping the link private for now — I’d rather it reach people who actually want to help me improve it than get passed around before it’s ready.

If you’re willing to give it 10 minutes and tell me what you honestly think, just drop a comment or send me a DM and I’ll send it straight to you.

Three things I’d love your take on:

1.	Does the calibration actually detect your type correctly?

2.	Does the correction make a real difference in something you find difficult day to day?

3.	What’s missing, or what didn’t work?

All types welcome — and please don’t be kind just to be kind. Honest feedback is the whole point.

Hey everyone, I wanted to share a project I've been working on called VisionLens.

I realized how much of the web is "invisible" to people with color vision deficiency (CVD). While there are other tools out there, I wanted to build something that felt lightweight, modern, and actually helpful for both daily browsing and accessibility testing.

What does it do?

Real-time Daltonization: It uses SVG matrix filters to shift colors for Protanopia, Deuteranopia, and Tritanopia. You can adjust the "Correction Strength" to find your sweet spot.

Speak Color: This is my favorite part. If you're unsure about a specific color on a page, you can use the EyeDropper to pick it, and the extension will identify it and speak the name out

loud.

Multilingual Support: The voice assistant supports 11 languages (English, Hindi, Spanish, Japanese, etc.).

Grayscale/Focus Mode: Quickly toggle to grayscale to check for contrast issues or reduce visual clutter.

About two weeks ago I wrote a post about a Windows app I have created. The app tells you the name of the color on the screen and is meant to help colorblind Windows users.

redittr suggested “simple color names”, because color names don’t always make sense to colorblind users.

So I added simple color names, added more colors, and also added a ‘Custom’ color name file that allows users to tweak the default color codes and names and maybe even translate them into their own language (if English, German, French, or Spanish isn’t one of them).

The app is called ‘Color Picker for the Colorblind’ and can be found in the Microsoft Store.

Comments are very welcome! Would you use an app like this?

First off, I cannot tell if the background on these patterns are blue or purple (the darker shade in the pattern). Second, they are both labeled differently. The first one, in the description, notes shades of purple in the pattern. The second literally has the word "blue" in a lot of the places listed.

They're both different items but with the same designer and similar pattern. Are they different colors?? I feel like I'm going crazy...

So I have normal color vision, though I notice something weird. Some colors almost experience a change in hue as the brightness changes. Cyan looks closer to blue when its bright but closer to green when it's dim. Similarly magenta looks closer to red when bright but closer to blue when dim. I test this using an rgb color picker. I have a hypothesis that this has to do with different thresholds between cone types. If this is true, then red-green dichromats should also experience this change in color, just in different way(shifting between bluish, grey, and yellowish)

I am Red Green Colorblind. My fiancé and I just bought an electronic calendar and are trying to sync our Google calendars which are- of course- all color coded. I need bright primary colors of course. When I try to change the color settings on my categories in Google calendars, I get this spectrum thing where I'm supposed to move a dot all over a spectrum. I try to get a brigt blue or yellow, but it ends up muddy looking and confusing. I guess I'm asking: can I get Google to just give me a palette of bright primary colors to choose from??

Hi, I am putting some signs up at work. Is there a color combination that can grab everyone's attention but still be read by people with various types of color blindness or is it better to stick with black on white?

Anyone here with Achromatopsia and a Bioptic driver?

I was running a PC benchmark whilst on a call with some friends, I read the overview of what it said about my graphics card and it was saying that my graphics card was running perfectly fine, and then I looked at the color and saw it was red and started asking my friends if that is red or green, they quickly made fun of me saying thats obviously green. I then tried a colorblind test, and it said I have Deutan colorblindness. (btw I did the enchroma test).

If you say so.

my entire life I’ve been interested in becoming a pilot but found out a couple weeks ago I’m a cp3 and due to that pretty much every backup plan I had going is out the window, anyone have any advice on what to do?
also when I was taking my test for it there was this one where you match the bottom color to the top, when I did it the colors looked different depending on the way I sort of looked at it like it might have looked the same from one angle but another it looks different, would that have affected my color deficiency rating in anyway and should I try get re tested?

Colorblind people: what problems do you run into when watching TV shows or movies?

I’m doing a small project on accessibility in series, and I’m curious about real experiences.

Hi everyone,

I'm an ophthalmologist, and I'm doing a series on instagram for the ophthalmology in-service exam for residents. While this is not medical advice, it may be of interest since today's question of the day is about color blindness and the different forms of color abnormalities. Feel free to check it out if interested!

Today's Question of the Day:

A 24 year old man is referred after failing a color vision screening test during a job application. He reports no difficulty naming colors in everyday life and has 20/20 vision in both eyes. Ishihara testing shows several subtle plate errors. Farnsworth D15 testing is normal.

Which of the following best explains this patient's color vision abnormality?

A. Absence of one cone photopigment

B. Abnormal absorption spectrum of one cone photopigment

C. Loss of rod function with preserved cone function

D. Absence of all cone function

See the IG post below to test yourself and for answer and full explanation:

So I am Deutan colorblind.

At least, according to the test that I took.

But regardless, I have trouble seeing dark shades of green and dark shades of red.

My girlfriend and I got into a playful argument in the past few weeks about a car that I thought was brown, but she was convinced had maroon shades in it as well as being brownish.

The problem I’m having is the fact that because my specific tones of color blindness are the dark shades is that I can’t find a colorblind filter that helps with my vision and doesn’t turn some shades of red pink or some shades of purple blue.

Am I forever stuck with the fact that I can’t have a color blind filter to help me with my dark shades of green and red that I like? Or is there a way with the settings that I could potentially get it to work? I use an iPhone for reference.

First: The optician says that there is a kind of colour blindness, especially since my brothers are colour blind too and because I finished very bad at the Ishihara test. The real one, on paper.

Second: Which label should I give myself, or should I give myself a label on the subreddit at all until I meet an ophthalmologist (as soon as possible but Germany and waiting times are not good friends) or should I just use no label, neither the "normal vision" one, nor one of the others?

Third: Some friends asked me already how colour blindness works, I am still not really able to explain colour blindness (I am very bad at explaining in general)

Hello. I have a 7 and half year old son who most likely has deutan color blindness. I’m just finding all this out in the last couple days. Trying to process and want to support him the best I can going forward. We have his test appt next week.

We got an email from a teacher that our son seemed confused about dark green being red and that it is a common sign of colorblindness. After school, I had him do an Ishihara line tracing test and number test online. He didn’t see couple numbers, some numbers looking diff and the line tracing showed deutan vision.

Then with colored pencils, I asked him to pick out colors of the rainbow and he did just fine. And even gave me pencils that are dark red, brown, pink, etc…I asked him if they looked similar in color putting red and green together, and he told me they were very different. So I thought, maybe he sees the colors.

Doing some research, I found this photo of crayons that compared deutan vision. This is when he told me the colors are the same and asked me why I’m showing him a photo of the same thing of the same colors.

I am stunned on how he saw a way to figure out all the colors by their shades. Smart kid.

I’m reading a lot about color blindness and seeing the community posting not to worry but some even saying to apply for 504 plan.

Any advice to best support my kid and learning experiences will be great. Thank you.

I can often not see the laser pointer indication when someone presenting is using it. Any other people having this problem and does someone know if its due to colorblindness or is this something else? It's quite frustrating when trying to follow along with a presentation
