i used most of the colors recommended by tk409 for my costume. everything was dulled down quite a bit by black paint.
one of the things that i really like, but is sort of tricky to get the hang of, is mixing rattlecan colors while the paint is still wet.
these were my 1st gauntlets, painted with the "claret wine" paint that 409 recommended...
and these are the same ones after their 1st repaint:
i still used the claret wine, but mixed in black. i sprayed a coat of the wine, then misted with black, misted with wine, then black, then wine... alternating very, very thin layers. eventually the colors sort of blend together to where you can't really tell that it's not just a darker shade of red. you have to be careful not to go too heavy with it though, or you'll get drips.

If you're lookin' to paint a helmet, then I'd recommend ya check out the site GCNgamer provided (darn Andy, ya beat me to it) as well as a few threads in the "Helmet" section because there are multiple people who are painting ROTJ helmets.
