Watched a presentation where the speaker insisted dark blue on black was 'high contrast' because they used a 4.5:1 ratio tool, but my buddy with deuteranopia couldn't read a single word.

Is relying solely on automated contrast ratio scores a dangerous crutch, or are those numbers the only objective standard we've got to prevent truly awful choices?

Oh man, my friend who's colorblind had the exact same problem with a chart at work! The numbers are a good start, but they clearly don't catch everything.

Totally agree with you @thomas_johnson35. It's wild how often basic colorblind checks get missed. Like, patterns or symbols on top of color would fix so much. Feels like a lot of places just do the bare minimum to say they tried, without really getting how people actually see things.
