>> Roads aren’t black. Your office chair isn’t black. The sidebar in Sparrow isn’t black. Words on web pages aren’t black.

I strictly adhered to the principle of never using black until I was specifically asked by one of my users that has presbyopia (and most people over 50 or 60 have it, to some degree) to make the text black. Black text was much easier for them to read than the standard Bootstrap dark colour with the same font size.
