It is always interesting for me, as someone who is colorblind (Protanopia), to see these. I always have to call my wife in and ask if the images look different. She is always amazed that I can't tell the difference. The original image and the Protanopia image are exactly the same to me. The Deuteranopi looks very slightly different -- if I really stare at it. The other do indeed look different.

This is really interesting to hear. I am also red-green colorblind (Protanopia) but the difference between the normal and Protanopia images here is very noticeable to me. I can see that red is missing in the Protanopia version. I definitely have trouble with many shades of some colors, especially if the colors are really small on the screen. So many Protanopia colorblind filters in games and apps mess up the colors w…

I agree about colorblind modes in games. One where I thought it worked really well was Star Wars Battlefront (2015). Instead of adding weird colour filters to everything it used alternate colours (blue and yellow instead of red and green for deuteranopia) in the HUD.

This tool deals with total colour loss, but does not allow for things like deuteranomaly which is far more common than Deuteranopia. Include a slider to simulate reduction in cones. As someone with deuteranomaly it's amazing how many interfaces just don't quite work.

Seems like it used to be available before: > Firefox 81 removed unnecessary simulations for protanomaly, deuteranomaly, and tritanomaly, and added a simulation for achromatopsia (no color).

I guess it doesn't serve a purpose.

Considering that these are developer tools, *anomaly-variants could be considered "milder" forms of the *anopia-variants, and further come in various degrees.

Further, people with the *anomaly variants can have severe headaches with certain color-schemes, and the best thing to avoid any misunderstandings, is to check for "safe-for-anopia", or/or use a scheme that avoids these altogether, which will also serve everyone on the *anomaly-spectrum.

But that's just my speculation.

I wonder a lot of about whether people with color blindness miss detail in life and nature, and how that affects them. The color blind simulation images are so drab, lifeless, and seemingly devoid of detail compared to the full color images.

I love nature and its vistas but there have been times when I felt I was missing out. A few times family members have commented on the beautiful shades of green or a field of green with bright red flowers in. And I just look at it and see.. A big mass of solid green.

There are "Enchroma" glasses, which increase color perception (in some cases) by blocking ambiguous wavelengths (particulary ones between red and green). These glasses are rather expensive, but it seems to me that such filter might be easily implemented on the electronic devices (eg. in the form of browser plugin).

It's definitely not easy or even possible to enable from software. For all intents and purposes displays have three different light sources, with three different fixed spectrum. You can't block a narrow band from red and green pixels from software to make them less ambiguous.

But it's like using polyfills and all that: if you don't want 100% coverage, you can at least play safe for 99%.

Cool.

Sadly the simulate button does not show up in any of my Firefox browsers (version 94.0.2)

Perhaps the feature requires a GPU feature not presented to the vGPU in my virtual machines?

Right.. booted up a physical box that I can access over RDP and there it does show up.

Would be nice to know the hardware requirements for the simulate option.

Let us hope this useful developer tool survives longer than some other parts of Firefox that were critical to my workflow: RIP, 3D DOM View (2012 — 2016) https://developer.mozilla.org/en-US/docs/Tools/3D_View

Not surprised Chromium added this after FF removed theirs.

I have a minor color blindness, I believe on the red/green scale. I can't get all the circles with dots in them, and I've struggled to find online tests that could definitively call out my type of colorblindness. The results vary by test site. Each one of the pictures in the Mozilla link look different to me, and I can easily see the colors that might be missing to others.

I completely lose my mind when I find visualizations that use gradiants of red to green and brown. For example, a US state map that will have 7 different colors of red, green, and brown with a legend for each on the side. It's extremely difficult to line up which color is assigned to a state. Line charts are even worse. Please just use wildly different colors and if possible, label the lines directly.
