@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.

@gsuberland fair point well made, but I've yet to see it done well/inclusively on any equipment that uses, specifically, LEDs to indicate status.

Manufacturers typically just don't care enough, and accessibility gets value-engineered out of the final product.

There's something weird (that you likely know far more about than me) about LEDs that make colours far less distinguishable than white light through a filter. To me there are two colours of LED: [red|green|amber|yellow] and blue.

@WiteWulf true, but the point of RGB here is that it's adjustable to any colour by whoever configures the switch.

RGB LEDs are narrowband (in the case of direct emitters approaching three Gaussian monochromatic sources). you get less radiant flux between the peaks so when you have anomalous trichromacy you aren't getting as much information as you would with a broad spectrum light source of the same colour. the effect will still be apparent for dichromats but to a lesser extent.

@gsuberland ah, this is along the same lines as why purple (which I can't distinguish from blue) isn't a real colour, right?
