Hello! I'm trying to realize some CSS customizations for some websites (Lemmy, Whatsapp, Startpage) in the style of the breeze theme (dark). I'd like to make it more universal by considering the accent color. and now my question... how do I obtain all the nice colors derived from the accent color, like for instance the highlight color of Dolphin files? there are many different shades of the accent color, but I don't know how to obtain it programmatically from css

sorry if it's a stuipid question but I'm taking the first steps in the CSS language.

thanks in advance!
