>Light background is a must. I never use dark mode on anything. Dark mode is fundamentally a hack around two things. First, shitty screens that can't run light mode anywhere near dim enough once the sun goes down (which is at least a 5-nines percentage of all screens ever produced). A good chunk of this is due to insufficient PWM frequency but software has a lot to do with it too- and if I can't make the screen go dark enough, well, then I'll just tell all the pixels to be black and use white text. Second, shitty flat UI design has made it more difficult to see borders between items. It seems to be easier to pick out a bright glowing spot in a field of black than the reverse- it's worse for comprehension, but not for identification/differentiation. It's easier to see that something is selected when you're using white-on-black, and if you already have a good idea what that something is the comprehension penalty is irrelevant. Those two things predate most proper dark mode implementations; I assert they created the need for it to exist in the first place.
