Here is "what a person sees vs what a dog sees." Do they look the same to you?

Do any of these pics look identical to the "normal vision" pic to you or all they all different?

Hi, I run an escape room and I'm taking steps to make it accessible to colour blindness. I've been told that using this palette will include 95% of colour blind people, I've come here to test that.

Lots of my puzzles run a red, green, blue, yellow palette, which isn't useful for some players

I've seen the IBM one and I can also make that work, but I worry that the indigo and the blue in that are too close to each other to be distinguished, however, I worry in this one here, the burnt orange and green are going to be indistinguishable to most colour blind people, so I'm asking the people of reddit

Whoever decided that this is better needs to meet me in my office immediately

According to a view from a paper, does this suggest that our color vision is often not as "flat" as simulators make it look?

I might have tritanomaly, not sure yet because my next eye doctor appointment in the summer sometime, so I'll bring it up there.

Anyways, on all the tests I take I get the same results, mild-moderate tritanomaly. However the comparison of normal vision and tritanomaly vision look very different. It's the same with this one video I watched that compares normal vision to tritanomaly. A good amount of the comments were "You know you have it when both sides look the same". But when I see it they look wildly different. Does this rule me out of having it? Have you had similar experiences? Are these people lying?

These are the results and correlating test titles that I took off the Color life website. I'm just recently piqued curious to the idea that I may have colour-blindness to some extent;photographic use of my mobile phone devices camera against my real-time perception of sight had me ponder on this or the past 2 years.

Peer based feedback review over the course of my young life in certain instances has made me feel that my sight was simply lacking in stylistic means and ways of taste, in anything relevance-related to a task/job that had to do with anything 'arts' media related.

Anyhow, I set up a Doctor's optometrist appointment for the June month coming up;but, I still wanted to do online tests in the meantime to have a compared mock view and syllabus clarity of 'what to think', 'what to ask', 'what Buzz words to use' and have some communication on the same spoken-theory level on the Doctor so that I can make the most use of my consultation time and I can just worry about the economic factor of the visit, because I am on a tight low-income wage budget and have to pay for the glasses for the condition after I finish-up the visit.

If you have blue-yellow deficiency, do these two colors with faint hints of yellow and blue just look black and white to you?

I'm building a website with a color pallet comprised of Navajo white and Oxford blue, to utilize the striking simplicity of monochrome photography while still having a slight colorful pop, even if it's not consciously registered. The first image has hints of yellow and blue. The second is pure black and white.

How do yall see it?

Despite its name, Eurovision has never been limited strictly to Europe. Over the decades, the contest has expanded into one of the world’s largest entertainment events, bringing together countries from across Europe and beyond through the European Broadcasting Union (EBU).

While most European countries continue to participate, several have withdrawn or been suspended over the years for very different reasons: political disputes, financial difficulties, poor results, disagreements with the voting system, or controversies surrounding participating countries and songs. Russia and Belarus are currently banned, while others such as Turkey, Hungary, or Slovakia stepped away voluntarily.

One of the most debated issues in recent years has been Israel’s participation, which led some broadcasters and audiences to call for boycotts or abstention. The map highlights how Eurovision is far more than a music contest, it has increasingly become a reflection of Europe’s political tensions, cultural debates and international divisions.

So I recently found out my best friend is colorblind, he cant see difference between gray and gray-ish shades of red, probably mild protanopia, anyways I wanted to prank him by asking him if he can see number XY and then show him a colorblind test picture where it says, “blow me”, or something like that.

Should look something like picture below.

Does anyone have like a tutorial, site, program etc to help me out?

Hello fellas. I'm working on adding a colorblind mode on my Chinese chess app. I figured I could start by simply inverting the color of black side images. Traditionally the color is only on the characters (second screenshot), which I suppose would be very difficult. What do you think? Would it usable? I converted the screenshot to grayscale for get an idea and I though maybe I could still increase contrast somehow.

Hello, I've recently posted asking about what color-blind type I was by labelling this color iagram space, but I decided to do it again because the original wasn't very accurate, which you can see in slide 1

Slide 2 is a little test I made for myself where I had someone pick random colors for me and I'd just describe it, I got 3 right and 3 wrong

I took some online tests, and while I intitally had thought I was deutan, I'm apparently protan, which really confuses me because I had always thought protonopia was not being able to tell the difference between red and green, and seeing red as green, while deuternopia was the opposite where u'd see green as red, correct me if I'm wrong because I probably am, but that still doesn't explain it for me, like red is a very distinguishable color it's out there with blue for me, like I can definitely tell it apart from green, I could only start confusing them when it's orange or yellow or brown, like show me a dark green ane a brown and I might not be able to know the difference, show me yellow and green I also won't be able to tell the difference, so how are my red cones worse than my green cones?

So I 3D printed a Crystal Slime from the Slime Rancher game (I didn't sculpt it, no way!) and I decided to color it with my choice of colours...pretty happy with it! I'm partly red-green and partly blue-yellow colorblind (yes both, the optometrist said I'm not quite monochromatic, but not far according to the tests! I confuse colours not quite completely in the fullness of both spectrum so...)

So the slime is a WIP still...about a week of drying (acrylic) then I varnish. I'm not QUITE happy with the whiteness of the highlights, but that's technique and I'll get better, but overall, I like it!

Why did I put this here? To show colorblind people that you CAN paint/colour (basically work with a colour medium) despite your fear of it not coming out well...if you like it (and I do like how the slime came out!), then that's all that matters.
