First theme created, how to find all possible configuration values?

Hi There!

I’ve been following Home Assistant for a long time and finally started with it some time ago. So far, great!
Got to build my first theme and quite happy with it so far:

what annoys me a bit is the color of the circle around the initials of the users name (red arrow in lower left corner).

I seem to be unable to find what value in the theme yaml file I need to add/adopt to get this right.
Does anyone have an idea what it could be or how I could find it?
This also raises the question for me if there’s any possible way/documentation to find all the possible values that can be configured in theme yaml file?

Thanks!

A few resources:

You can also use the chrome dev tools to find the variable used in for a specific item. Sorry don’t have a good link that explains how this is done.

I tried the dev tools but couldn’t find them.
Very useful information, will try them out.

Thanks!
