They haven't had a special edition red. But they already have the TorRed and the Inferno Red, so a 3rd red would probably be lost in the crowd.
I could see doing some kind of special black. The Brilliant Black Crystal Pearl has that little bit of sparkle to it. I could imagine some kind of blackout edition where they do either piano-key type black, or a matte black, and then have some special black wheels or something to go with it.
Dodge, if you are reading this and steal my idea, I do accept payment in car form.
