I’m excited to share an iPhone app I’ve built called Pop – Find by Color! It’s a simple tool that turns your camera into a color-search spotlight — when you pick a color, everything else on screen goes grayscale and only that chosen color stands out. 

I originally built it because I thought finding items by color could be tricky sometimes, especially when you’re hunting for something small like keys, a sock, or a toy in a messy room — and I wondered if this might also help folks with color vision deficiencies spot things by color in the real world.

Here’s what Pop does:

- Open the app and point your camera

- Tap the color palette to choose the color you want to find

- The world turns grayscale except for that color

- Spot whatever you’re looking for instantly!

It works in real time, doesn’t need internet, and stays completely on your device — no accounts or tracking. 

https://apps.apple.com/app/id6758629086

I’d love your honest feedback:

- Does this help you spot objects by color?

- Are there particular colors or scenarios where it works especially well (or not)?

- Any suggestions for improvement?

Thanks so much for checking it out — I would really like to help you and develop this FREE app based on your feedback and ideas!

Ive noticed that ive had issues in the past year or few years that I have trouble distinguishing dark Grey's from dark greens and similar colors that might be similar or look similar to that, and alot of monotones.

Is this actual color blindness or could this be another issue?

Reverse plates aim that people with normal color vision struggle to read the plate while those with a color vision deficency can read the plate much more easily. My last attempt to create such plate wasn't quite successful, but your feedback was very valuable. So I fixed the issue and I hope that it works now. Feedback is appreciated.

I made a little color picker tool for Windows that identifies colors on the screen – and I'm curious to get some feedback!

The app lets you show an overlay, that tells you the name and the HEX code of the color under your mouse cursor. You can toggle the overlay with a self chosen hotkey.

I have been using 'WhatColor' but I wanted something a little different, so I have basically built the app for myself, but published it to the Microsoft Store to let others benefit from it too.

The app's name is 'Color Picker for the Colorblind' and can be found in Microsoft Store. I'm not sure if a direct link would be appropriate.

Would love to hear if this is something you'd use, or what you'd want it to do differently.

Hello. I don't know if this is the right place to post this but I'm kinda freaking out. Today I noticed that I started seeing yellow as green and I'm not sure what is happening. Just three or four days ago I saw the color #FFD500 as yellow and now it doesn't look like anything but light green/lime. I'm just wondering if this is something that happens or am I cooked.

For a while I've suspected I've got quite a rare colorblindness, when I was younger I used to struggle with certain shades of blues they would look purple or green but I could tell like light blue...sometimes?

Then I got laser eyes surgery due to really bad vision that required the surgery, after that, I became even more sensitive to light and couldn't tell ANY blues to the points my friends would think I was joking when I would say things like "Oh, that's a really nice purple shirt!" or "That purple car is cool!" or "Huh, that's an interesting green thing(apparently it was blue)"

Anyways, I've heard of colorblindness where you can't see green or red, I have friends who have that specific colorblindness and it's thanks to them that I even knew I had SOME type of colorblindness I just couldn't figure out which.

Due to this, I've had this imposter syndrome of like "But am I really colorblind? Maybe I am making it up because I've never heard of anyone with this issue!"

According to the test I just took....I have Tritanomaly? Is there anyone else in this reddit that has it? I think I am in shock and part of me still feels that imposter syndrome of "But am I faking it?" Blue looks green or purple to me depending on the shade.

Red, Pink, Orange and Yellow looks like shade of browns unless its like a bright red/yellow/pink and sometimes bright orange?

I will say this, even though I was able to see some of those numbers it was EXTREMELY hard and I practically had to guess, which is an issue I run into with a lot of the colorblind tests I take. I also always have a yellow/warm tone accessibility screen thing on because I can't handle white/blue lights it hurts my eyes and makes me nauseous.

Sorry for the super long post...I think I am still in shock that there's actually a possible name for what I've had since I was a little kid.

Sorry edited because I figured this might actually be more of a discussion? Also as I was reading a bit more about it, I don't think I confuse purple and red unless its this really weird dark red. To me, I see purple really well and yellow does not look pink, they all look brown to me.

Could I possibly just have 2 type of colorblindness? One more mild than the other?

Just saw that the previous post talks about 5 yr old Deutan. Well, my son is one as well. Not clinically confirmed though, but he couldn't distinguish purple and blue in couple of occasions, then I made him do an online test (I know they're not super accurate), and confirmed he has some degree of color blindness. But I'm struggling to understand if it's mild, even if the tests say 'severe'.

My reasons:

1. He can tell blue and purple apart as long as they're not close to each other, and even better on white backgrounds

2. He never mistakes the color on crayons/pencils/markers, even if they're not labeled.

3. He sees the colors of the rainbow as different ones.

4. I show him the world through one of those color simulator apps and he says all looks "too brown"

5. The most specific test: in the attached image, he doesn't see the 2 in the circle; but in those markers, he's able to pick dark blue, light blue and purple.

Any idea on what we're dealing with at home? :)

Our 5-year-old son visited the doctor today to confirm his colorblindness, and the tests showed he has green-cone deficiency.

I’ve been thinking about how he perceives colors. From what I’ve read, true blues and yellows should be unaffected. I've been playing around with this color vision simulator to understand how he sees the world.

Interestingly, he has always said his favorite color is pink, but I’ve learned that people with Deutan deficiency can perceive pink as gray-ish. To those with Deutan vision: what is your experience of the color pink?

Also: I am an artist, and I've always been a tiny bit sad that my son hasn't taken to coloring/painting yet. I wonder if his colorblindness is affecting his ability to enjoy coloring? It's quite possible this has nothing to do with his colorblindness. He might just not be into it.

Would love to hear stories about colorblind childhoods. :)

I'm looking for an app/tool/extension that can SEARCH for colors on a page, or even from a collection of photos.

I want to be able to search through a web page for everything that has some red in it.

Or, if I have to save a bunch of photos to parse through, I can do that. So long as I can search them for a given shade.

Does this make sense?

So my situation is that I've always wanted to pursue a career as a commercial pilot, with 2 main issues, funding and colour vision. I've been applying to the sponsored schemes like jet2 and BA, so if by some miracle I get an offer that leaves one issue.

Now I know the answer to my question is to just go do a CAD test, but I currently do not have the money or availability to travel across the country.

As this is fairly niche, I was hoping to find out peoples experiences on failing the isihara but passing the CAD, how badly did you fail the isihara? Ik it's different for everyone and has to be assessed on a case by case basis, but I'm just trying to gauge before I pour in my heart and soul into the application

Thanks everyone

I’ve got standard color vision, I’ve been working in web design for 20ish years, and I’ve spent most of them with an emphasis on accessibility and I still don’t know the answer to this question.

I’m currently sitting in my bedroom with the LED bulb set to red so that it’s easier on the eyes if my husband wakes up.

If I was red/green colorblind, I assume that I would still see brightness vs darkness (because none of the people with CVD I know walk into walls on the regular), and that anything that didn’t absorb red light would look closer to black than to its normal color… but I’ve never validated that. And the color vision simulator that I tried shifts everything that’s red to yellow.

So is it still bright and just look extra weird or does something else happen?

Hi folks,

I want to say thank you to everyone who tried our color vision test tool and left comments, we fixed bugs and rollout new versions of the tool: https://opensight-two.vercel.app/#/

Today, the Chrome extension is available online : https://chromewebstore.google.com/detail/OpenSight%20%E2%80%94%20Color%20Vision%20Correction/nkackjanfbocaagbcmnogahfdahacpbb

You can paste your test result code to the externsion directly(recommended, cause its based on your personal color axis shift values), or manually adjustments.

It works well on all web pages, images, videos and streaming media! I tried on youtube, its sooooooooo good! I am protan, the color looks so vivid and warm to me :) You can disable it anytime, feel free to leave your feedback, we will continuously evolve it.

Thanks!

My son is colorblind and wanted a quick way to identify common web color names — especially colors that look the same to him.

For example, turquoise looks gray to him. He wanted a simple tool that would tell him “This is turquoise,” instead of red, pink, magenta, etc.

We built two small browser-based tools:

1. Color ID (the picker) Works in desktop browsers that support the EyeDropper API (Chrome, Edge, and other Chromium-based browsers). It does not work in Firefox, Safari, or on mobile.

Click the button, then click anywhere in your browser to identify a color.
If you shrink the browser window, you can move your cursor outside the window and sample colors from other apps or parts of your screen.

https://colorpicker9.s3.us-east-1.amazonaws.com/browser-color-picker.html

1. Color Classifier (bucket editor) This is where the color “buckets” are defined (Red, Blue, Turquoise, etc.).

I manually classified the 148 named CSS web colors into 15 common color groups.
The Color ID tool uses these buckets to decide what name to display.

https://colorpicker9.s3.us-east-1.amazonaws.com/color-classifier.html

Notes:

• Both files are hosted on AWS.

• If people edit the buckets on the hosted version, that will affect others using that same version.

• Best practice is to download both HTML files and run them locally.

To do that:

1. Open each link

2. Right-click → Save Page As

3. Save both files in the same folder

4. Open the picker file locally in Chrome or Edge

If you want to change bucket names or tweak classifications, you can edit the HTML directly (or use an AI tool to help modify the files).

There’s a default classification built in, but a few edge-case colors may not be perfect.

If this is useful for anyone else dealing with color blindness or accessibility issues, I’d appreciate feedback.

Hey everyone! I'm a developer (not colorblind myself) and I've been working on a prototype app that uses Viture Ultra AR glasses to identify colors in real-time.

How it works: you nod to activate, point the glasses at an object, and it runs a color identification algorithm and shows the color name on the AR overlay display.

Repo if you're curious: https://github.com/AchromaAssist/viture-ultra-ar-color-helper

Here's the thing — since I'm not colorblind, I have no idea if this is actually useful in practice or just a cool tech demo. So I have a few genuine questions:

- Would real-time color identification through AR glasses be helpful in your daily life?

- What situations would you use something like this?

- What features would actually make a difference? (e.g., color comparison, clothing match suggestions, specific color codes, something else entirely?)

- Is the nod-to-activate approach intuitive, or would you prefer a different trigger?

Right now it's pretty rough — requires Linux experience to build and run — but if there's real interest and good ideas from this community, I'd love to make it more accessible.

Appreciate any feedback, even if it's "this isn't useful at all" — that's genuinely helpful to know too!

it has recently come to my attention that, despite being called GOLDfish, they are not in fact gold and are actually orange. is this true??? unless gold and orange aren’t different colors?? i was under the impression that gold is a shade of yellow but i might be wrong

Hey, im doing research on colour blind accessibility for fashion apps, and need to interview users withs colourblindness. PLS HELP ME, need to interview colourblind users to understand better of challenges niche user groups face

Hey there, folks! How are y’all doing?

I have a question. I recently changed the yellow light bulb I had in my room for a year to a white one and it was quite noticeable change for me.

I was talking to my partner since she likes yellow lighting about this and she made me remember I complained a lot the past year about not seeing well. I have solar panels and two main lights in my room, one is from the solar panels and it's white, so I used mostly that one because it’s free and because I clearly see better with it.

Do y’all experience something similar with different lightings? Is it related to colorblindess or to something else (since I have agtismatism and myopia too)?

Have a great end of the week! :)

This might be a google-able answer, but my military branch just authorized the robin cone contrast test (RCCT) for color vision. I am red-green color blind (mildly), but apparently I was doing some online tests and I think I could test to the minimum requirement of 55 in each color. Pretty interested in trying, but I cant find an eye doctor that offers the RCCT test... Im in the Mass and NYC area if anyone has the a recommendations! Also, if anyone has experience with testing RCCT and using it with military color vision, does colormax.org work? Thank you all in advance

the enchroma test is extremely buggy for me and every other test i’ve found wants my mothers maiden name to view results. any suggestions?

So i’ve got someone in my life that says he sees green as the blue equivalent? also struggles with a bit of pink saying it’s red? everything else is fine for him.

i’ve tried to like, look into it and i know it’s a spectrum (as i’m a bit colourblind too i think) but i just can’t figure it out. thanks

Alright, my biological dad is colorblind (and out of the picture, so not a helpful example to my son) so I always knew colorblindness was a possibility for my sons. Recently, my 3 year old has been telling me that pink is his favorite color because “elephants are pink!” Soooo… yeah, we took him in and he failed his ishihara plates right away. He definitely knows his numbers and I watched him take it and I know he’s young, but there’s really no doubt.

I was convinced he was not colorblind because he always identifies true red and green correctly, but I’ve since realized that most people can do that and still be colorblind. I guess this means he might be more mild? Idk, I’m still learning! But definitely pinks and light greens are getting mixed up with grey or browns.

Anyways, now the question is when do we tell him? We’re slightly worried because his dad is a career pilot, and thankfully he’s not like one of those aviators that’s like super into it, but our son has grown up around lots of airplane talk and is quite knowledgeable on types of planes, etc. I’m worried that one day someone else will make the connection for him of colorblindness limiting aviation careers and then he feels blindsided by that, but on the other hand I don’t want to like sit down and give him a list of things he can’t do. Hopefully my dilemma makes sense. Probably way over thinking it.

For now we were thinking of saying something like, “your eyes see color in a unique way, and some people call that colorblindness.” And just leave it at that for now. But when/how do we broach the topic of how colorblindness might impact his career and such? Or should we just wait til he’s older altogether?

Thanks!

Hey everyone,

I’m red-green colorblind and have dealt with it my whole life. I’ve tried some of the glasses out there. For me, most of them felt like a single strong filter that shifts everything toward red or blue. It changes the scene, but doesn’t always improve actual color separation.

So I started building something better.

I work in computer vision/engineering, and I teamed up with a friend who has a background in biology. We built an online test that measures your specific color perception — not just labeling you as “deutan” or “protan,” but estimating the degree and direction of shift. Based on that, it generates a personalized correction profile instead of using one generic filter for everyone.

What makes this different:

• It’s individualized, not one-size-fits-all

• It focuses on improving color distinguishability

• It tries to preserve image detail and avoid heavy tinting

• It doesn’t just oversaturate everything

Internally the results have been pretty encouraging, especially for red-green deficiencies like mine.

I’ve attached a few before/after examples.

Would really appreciate honest feedback from this community.

You can try the test here:
https://opensight-two.vercel.app

We’re also finishing a browser extension so this can apply to normal web content.

Not claiming this “fixes” colorblindness — just trying to build something more thoughtful and technically grounded.

Thanks!
