Wheels painted in solid Pastel colours look great with silver, something like Pastel Peppermint Green could look very cool, and also some of the real old school VW colours from the 60's and 70's
Metallic colours other than Silver and Gold should be avoided, as they can look very naff, and Anthracite has been done to death for far too many years
Use this to find the correct colour for your wheels,
Find the area/segment that closest matches your cars paintwork, then look at the colour 180 degrees opposite, this is your ballpark colour for you wheels, this system is used everywhere! in advertising especially! because it works, nothing is by accident
