Dark/charcoal grey is better than pure black for text. But it's still dark enough that most people would call it black.
The problem is contrast, really. Some color combos are terrible, and you also have issues with color-blindness (which is why gray is used a lot).
Gray text, against a gray background, can suck.
I’m getting on in years, and low-contrast text affects me a lot more, these days, than it used to.
It's not, that's a myth. The blackest black your monitor is capable of is best for text.
so wrong
