For 33 years, My terminal windows've been #FFFFFF background w/ #00000 text. My thinking when I was 18 years old was that I wanted my windows on the computer to look like paper. I generally only used #FFFFFF on #000000 on airplanes as laptop LCDs could be seen from more angles that way.
With so much display in my face, I am wondering if this is too intense, so I'm trying #FFFFFF on #00000 for a while.
BTW, for #Emacs, I always (&still) use #000000 on #e5e5e5 (or "linen"), which is a bit softer.
@bkuhn Have you ever looked at the solarized color schemes?

@trini My goodness, I feel old as I didn't even know what that is!

I just read https://en.wikipedia.org/wiki/Solarized & in fact my #000000 on #e5e5e5 Emacs colors look very close to solarized Base3. (My Emacs windows look a lot like: https://upload.wikimedia.org/wikipedia/commons/b/bd/Solarized_Light_Xcode_4_Theme_%285592863390%29.png (except I don't write Objective-C of course🤣).

So maybe I actually invented light solarized in 1993 when I picked black-on-linen the fist time!

I never used the #e5e5e5 for terminal windows b/c I wanted to distinguish them visually from #Emacs easily.

@bkuhn Might be worth heading over to https://ethanschoonover.com/solarized/ and playing around with some of the options. Having gotten older as well over the years I've found using these on most things has lead to better readability in general.
