Start with a red (or other color) pinstripe, or double pinstripe, and see if that works. If it doesn't, then change the color completely.

 

I like the bronze, gold, and silver. I don't care for the red or green, too flashy for the rest of the car, but that also assumes you have no future plans to add flashy color to the exterior look. I think the dark grey looks like a dirty black.

 

I still like the idea of blue though...

As far as the pinstripe idea, it might look good to pinstripe the edge of each spoke (so it would be red-black-red going across each spoke) and continue that around all the edges. Then you could pinstripe the edge where the wheel meets the tire. I dunno, interesting idea though.
