Why don't you just look at
gw's website?

Charadon Granite also isn't actually technically a "gray".
It's a blackish-olive brown. And it's a
fantastic basecoat for whenever you're painting black on a model.
As for Adeptus Battlegray...
It's about two shades lighter than Adeptus Battlegray, and is close to Vallejo's "Neutral Gray" color.
