What is the best background to make on a site for text?

Question

Design

It seems to me that earlier they used beige, pastel colors more often, but now everyone has begun to use a white background + black text. What is it connected with? What problems with perception can occur when using a slightly gray background? Maybe the gray letters blur more.

The only rule is that the text should be contrast enoughso that you do not have to strain your eyesight when reading.
