This is a very informative and well structured post. The clarity of thought and experimentation methods that led to the final solution was a pleasure to read.

Also, the problem space is one that I haven't thought about, but probably should. After all, accessibility should be important to all of us.

I kind of wish the OS Vendors were not asleep at the wheel, and had features to address these issues as a 'built-in' value proposition for their products. I mean, it seems to me the sort of thing that a computer ought to know how to deal with, inherently .. and sure, some vendors do make an effort to make these kinds of human differences accessible. But its just .. well maybe there is a broader malaise with OS vendor…

Not sure about iOS, but Android has multiple color blind settings built in.

iOS does too, along with a number of other display accommodations. It has adjustable filters for specific forms of color blindness, along with an Ishihara-like test pattern to help tune the filter to your specific needs.

I have a legit question. Do colorblind people use some extension in their browser? This post gave me the idea that maybe some extension could show them the warnings and some options to scale the colors in an appropiate manner. My first idea was to try using it in development, to check how colorblind people see our apps and provide a solution. Do you have any further plans or ideas with this? (It's an interesting topi…

I suffer from deuteranopia and use the Spectrum extension in Chrome from Yehor Lvivski. It's ok for switching between different color modes so I can see differences in them. I am intrigued by the Enchroma glasses, haven't wanted to gamble $300+ on them yet.

Not colorblind myself, but I often use spectrum as a final pass to make sure any colors I've chosen for a UI aren't going to cause issues. I just hope it's decently accurate.

I'm also a very heavy F.lux user, so all my color choices have to be usable with an orange filter as well.

Excellent tool. Our organization is AAA compliant with the ADA section 508 (details for anyone who needs them: https://www.section508.gov/content/build/website-accessibili...), and color is a major issue.

One suggestion for designers & developers who need to be ADA-compliant: part of the spec is the level of contrast between different colors. We currently use WebAIM to check our color contrast: https://webaim.org/resources/contrastchecker/

I'd recommend looking at the contrast levels needed to achieve ADA compliance, or any other compliance needed depending on the regulations in various countries, to make it easy for designers & devs.

Disclaimer: I'm colorblind. There are SO MANY designs that use indistinguishable colors for no good reason at all. It's perverse that League of Legends uses blue and purple as its team colors—literally anything else (blue and red is my vote) would be easier for many colorblind users to tell apart. And a lot of heatmaps use gradients that go from blue to purple or from red to green…why‽ I'm willing to admit that the v…

Red and green are particularly easy to distinguish for people with normal vision because the sensitivity spectra overlap so much. So when you don't consider colorblind people it's a very natural choice.

It's also fairly easy to have a colorblind mode that swaps the pallet to something. People generally only have 3 color receptors, but color blind people don't all share the same 2.

Your comment reminded me of the talks on the issue of information display for Matplotlib[0][1]. I think a lot of design is done without awareness of accessibility and this is more broadly a cultural thing than a technical thing. The situation can be improved both by technical means (OS or hardware awareness) as well as by our collective education about what kinds of issues designs should consider. Typically, designs…

FYI, recent versions of iOS have a zoom / light / color-swap tool built in. You can enable it in Settings => General => Accessibility; it's called "Magnifier".

FYI, you should reissue your certificate. Chrome 66 is already blocking it (because of the Symantec fiasco). https://i.imgur.com/dWqeK74.png

er, I switched to firefox when it became a good browser again. will see what I can do about the cert. thx

League of Legends offers a colorblind mode in game that does exactly that - changes the teams to Blue and Red from Blue and Purple. IIRC, they even use that mode for their E-sports tournament streams - but I might be wrong on that as I haven't watched any LoL tournaments in quite some time. E: Just tuned into the EU LCS to take a screenshot - and it has colorblind mode on: https://vgy.me/ijQgrR.png

World of Warcraft got colorblind mode in patch 6.1 (around feb 2015) [1]. Before that, one needed to achieve this via addons (with varying effect).

Ah, had the wrong name, but that's what I was referring to with my discussion of "Zoom". I love the magnifier and use it all the time.
