Tags Colored by Group

I think this would be a good feature to have as it'd allow users to see what group a member is in at a glance without having to hover for the profile summary. Other forum hosts also have this feature whether it's by default or via CSS.

This is already possible to have your username colorized by groups.

Since I am in the administrators group, my username is red.

Could you please explain in more detail ? better with a picture
