Quite honestly, there really isn't much you can do about it. If he did in fact steal the header graphic as you said in the other thread, and you owned the copyright to that graphic, you could probably email his host and say he's illegally using copyrighted documents. They will either tell him to remove the file or do it themselves.
But about just the color scheme, there's really not much you can do.
Please don't turn this into another fighting thread or I'll have to close it as well.
