Well, that isn't simple. I have my PC set for different colors for each tag and there are roughly 100 CSS statements to do that. Before plunging into that, you may want to read up on use of the userChrome.css file and its many options, most of which are not documented in any consistent place.

I made my userChrome.css a long time ago, but TB changes so often I don't want to go back to it :-)

Well, since you're literate on the topic, here are settings I use for dark theme. However, if you ask me any questions on it, I'll cancel you out of my will. But do experiment as you desire.. :)
