Please Stop Using Grey Text
> For over 1000 years black text on white paper has been the best practice for printed texts worldwide.This alone almost made me stop reading the article.  What worked for printed text has no bearing for what works on an illuminated screen.But honestly, it's not grey text that's the problem. I agree with the author that maintaining high contrast is important, but it is equally important that things aren't too bright.  You should avoid using extremes like #000000 and #ffffff unless you're really trying to make something highlight.#0f0f0f or even #202020 doesn't make an appreciable difference, at least to my eyes. Believe me, as a 50+ year old, I notice when it's hard to read things.
