I'd like to be able to set the default colour of the text on tabs. As of now it defaults to the system colours (as far as I know) that come with the theme. My usecase is sort of like this: I'd like tabs where no activity has taken place to be displayed in a dark grey colour, tabs where there's been activity to be black and tabs where I've been mentioned to be blue. Right now the "base" colour is black, which has me using two nuances of blue for activity/mentions and it's not quite like I want it to be.

Reproducible: Always
