    It’s called RGB because there’s a red, green, and blue diode. Not sure how that’s not a logical name.

      Oh I was making a joke cause it sucks at purple. Which is red and blue combined generally. But that’s not really how the RGB color cycle works as far as I understand in some extremely cursory Wikipedia reading lol

        IIRC, it has something to do with the fact that purple sort of doesn’t actually exist. As I understand, purple is basically your brain going “idk wtf it is but it’s not green”
