As someone who is mildly colorblind, but not nearly as color deficient as others—Please please please use actual colorblind testers. I have seen testers with full color vision test color contrast ratios based on edges only (pixels) of text affected by font anti-aliasing. This is pointless and serves to dilute the premise.

Also test your new UI on older people. The older you get the harder it gets to distinguish between things with low contrast. Apple is really bad at this with the newer MacOS design, but obviously not the only once. It is like old people don’t use computers, and yes, it will happen to you to.

  It's not just contrast. It's also font size. It's also the font itself. All websites should be readable in Firefox or Safari (or Chrome but I don't use that) with the minimum font size set larger than the default. I use 18 min and a lot of stuff breaks. I'm sure that other people would greatly benefit from even larger fonts. I don't care about "pretty". I'm resigned to not getting that. But a lot of text simply disappears when the minimum font size is bumped up. At least Firefox manages to render most sites at a decent size when I set 18 min. Safari, for some reason, still struggles with that. Also, I generally read everything using Lucida Grande. It's a nice legible font. Firefox allows me to force that font. Safari doesn't. Just how fucking hard would it be for Apple to let me choose my own font in Safari?

Technically not "let me choose my own font in Safari" but you can set a user style sheet which overrides fonts. https://kgrz.io/safari-custom-user-agent-css-overrides-using-webfonts.html https://kgrz.io/safari-custom-user-agent-css-overrides-using...

      Tangential: it would be nice if `@font-face sans-serif { … }` (likewise for other generic families) was a thing in user-injected stylesheets. Especially when you don’t have such options in UI.

Testing for color blindness and contrast is an area of accessibility where the tools are actually very good. Even the built-in tools in every browser will tell you about contrast levels. There are enough variations of color blindness and visual acuity problems that relying on manual testing probably won't catch much.
