A #000 pixel on the screen of your mobile or laptop isn't black, either.
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.
- yathern 8y agoYour concern for less-than-perfect sighted users is laudable - however, there are accessibility specifications for contrast you can adhere to (4.5:1 I believe), to ensure your text is readable, without having to go #000 black on #fff white in all cases
- TheOtherHobbes 8y agoCan confirm. I'm >50, and I found the not-really-black text very hard to read.

- amluto 8y agoHow do they define contrast? Is it the actual linear light (gamma corrected) contrast or are that saying that, if R==G==B, then you want R1/R2 >= 4.5?
