Is it possible to have color coded forum threads?



New poster here. I have a forum with a private and public forum. The private side is completely private from view except by certain member groups.

In our old forums we had the public and private forums color coded with just slightly different color background.

That way, when you see a new thread list, you are able to differentiate quickly if it is a public or private thread.

Is there a way to do this in XenForo? Thanks!
