I think silver or white wheels on a white car looks pretty boring, yet being a white car the wheels have soo much potential to look awesome!
Anthracite is definitely the way to go, regardless of what alloys you decide to fit on the car. Anthracite is a popular colour for wheels, but how many cars with this wheel colour are actually white?
Black is also a really sweet contrasting colour, but doesn't always look right - this is easily overcome by leaving the edge of the rim silver, or on an older car fitting white walls! Sometimes gloss black wheels can look tacky, where-as mat black doesn't do any favors.
Alternatively if you didn't want to turn to the dark side you could go for a nice glossy solid mid-grey.
I'm not at home much at the minute otherwise I'd help you out with them photoshops.
