I have seem copper plating in the chroming process but wondered if there are copper or bronze colored wheels?
The copper is just a necessary base upon which to plate the nickel and then the chrome top coat. For many practical reasons, nobody supplies copper or bronze plated wheels as the surface would rapidly corrode and the tyre bead would no longer seal. But there's nothing to stop you getting any wheels you like and having them painted in those colours. Or you can fit magnesium alloy wheels which have a similar colour although it's closer in shade to brass rather than bronze or copper.
