I still set orange text on black for my Linux SSH terminal connection, with a blinking block cursor. It gives a retro 'mid century unix' vibe.

Back in the day, orange was the 'posh' colour for monitors, whereas us common people had green screens. Some freaks inverted the monitor to have black text on a green screen - as that was closest to using 'real paper'. Some old timers still used real (toilet) paper teletype TTY terminals, but only because their eyesight couldn't bare the new retina burning VDUs. And then came along the ZX80 with black text on a white TV screen, and we were all converted to light mode. Until someone produced a video inverter and we went back to dark mode...

On the subject of Dark Mode, is this like Apple zen mode? ? ? ? I have no idea as technology moves so fast  :-//

I believe the overal luminancy of the screen should be about the same level as the background lightning coming
from behind the screen (wall, room, etc.) in order to avoid eyestrain.
So neither black or white is a good choice as background color. Personally, I use some kind of "sand" color (#ffec9d) and black text.
