I am fully here for the move to RGB LEDs on network switch status ports. it's one of those features that sounds like gamer gimmick bullshit but is actually super useful.

@gsuberland hard nope on that: utter shit UX for people who are #colourblind.

There are three guys with CVD in my network team, a statistical anomaly for sure, but 1 in 12 men are colourblind, and 1 in 200 women.

@WiteWulf I'm aware of the stats having rather heavily studied human visual perception. achromatopsia is extraordinarily rare, so CVD-safe colour sets are entirely doable here, especially given that the subset of CVD that makes up 70% of CVD prevalence is served with a single common distinguishable colour chart. the feature itself is fine, it just needs to be used in a way that's inclusive.

@WiteWulf there is, of course, a slightly smaller subset of colours that are distinguishable by everyone but the achromats, which works for literally 99.9999% of humans, which is pretty cool.

also, random fun fact, of the 0.0001% of people with achromatopsia, the majority only have it in one eye because it tends to only affect one hemisphere (bilateral achromatopsia / hemiachromatopsia)
