Username Colors

Hello,
I have seen other sites do this, but I am not sure how. You see, I would like to know how members can go to their profile and change the color of their username. Say, they wanted each letter to be a different color. How would they do that? Because I would love if my members could. Warriorcatsrpg.com does that sort of thing, and I would also like to know how to do it.
Cheers!
Beetee.

I don't think that's possible.

Yes, as Joph25 has stated: this is currently not possible. The only way of changing a member's username colour is to add them into a group. If you wish, you may suggest this idea (make sure you do a search beforehand) in the Suggestions for your forums section.
