Light colors should stick with bright rims IMO. My new wheels came in a gunmetal and I hated it against my white. I dipped it in "bright aluminum" plastidip and now it looks like the stock color. So my pick is stock aluminum color. I don't think I'd like the mineral green with bronze combo either way.
