Colored Usergroups... question I've been wondering.

http://punres.org/desc.php?pid=56

We installed this plugin, and it works, inside of posts, mods/admins names are blue, and at the footer, the names are blue... but what about elsewhere?  Such as the "last posted by", area?  Or anywhere else that would have the names we changed in color to be the "default user" color?  Since we want the color to be a universal change on the boards from default color, to our edited usergroups color.

See what I mean?  We're just wondering if it'd be possible to make the typical color in some areas take the change we did.  We are still learning PHP, so, this question, if answered, would help us out.

I posted this at PunRes, but I thought I'd give it a go here.
