Photoshop users?

Hi, I am thinking about getting my stock rims painted on my 2007 Sebring. If anyone with photoshop experience could change my stock rims to fully black, gunmetal, and stock with black accents it would be much appreciated. I am trying to determine what each color would look like before I do anything.
