Welcome aboard RollaGirl :P
You can either the Ford True Blue, the Blood ORange as mentioned above as crazy color, the Phantom Purple or the Yello on the new XR6 is pretty hot. Hothouse Green from the Holden's looks good. Don't touch Tiger Mica (that's my color :P ) uhm, the Ford Probe purple would be a different color to get, it's got a light chameleon effect in it.
What colors did you have in mind?
