So neither black or white is a good choice as background color. Personally, I use some kind of "sand" color (#ffec9d) and black text.

For decades my preference is "255 235 205 blanched almond" or #FFEBCD, which is similar albeit paler and warmer
Gyro:
Back in the day (monochrome CRT) white on black (well CRT face) looked better for a given video bandwidth. On standard 80 character terminals, a 'white' background showed up the scan lines and emphasised any ringing on the video. As others have mentioned, it also resulted in lower average beam current and possibly better EHT regulation (blooming on screen blank).

Phosphor  ;)

No it isn't. When you're older, you'll understand.  :P

Indeed, I love dark mode on my phone, I find it much easier on the eyes. On a desktop it depends, I have some dark text editors that are visually pleasing but I can also work on a white background if there's at least something darker around it. A lot of times I find dark mode too dark and light mode too bright.

Presumably, on new fangled OLED screens, dark mode significantly reduces power consumption.
PaulAm:
The world really didn't begin with Apple IIs.  Prior to microcomputers there was a large time sharing environment with remote access by serial terminals (eg Teleray) and other protocols (eg IBM).  IBM CICS systems used a green phosphor and were widely deployed (I think you can still find CICS terminal emulators around).  This is like the mid to late 70s.

Power saving?  Nobody even considered that until after the oil shocks caused an energy crisis.  The world looked very different then.

I suspect (and may be wrong!) that you both have your white point or color temperature set too high in your monitor, like 9300K. In comparison, 6500K white point would have all white look similar to your preferred "blanched almond". As a bonus all colors will be more accurate since pros with color-calibrated monitors usually use this white point, so most content is produced to use it. Sadly most monitors come preset to the eye burning highest white point, just as most TVs come preset to Vivid mode, with high color temperature and boosted saturation, contrast and sharpness, because somewhere someone decided it looked better or at least more impressive.

I have no idea of the temp settings in all the CRT/LCD monitors I have used since the late 80s! Nonetheless,

* blanched almond has been my preferred option
* on both current monitors the difference is as I notedAbsolute colours are a different kettle of fish, a rathole which I have avoided like the plague.
