Well here's a couple of different wheel finish colours I could try on my interlagos winter alloys..... Obvioualy I've done these in photoshop and I'm by no means an expert in using this software. But it gives a bit of an idea how anthracite and black may look.
As now

Anthracite Finish

Black Finish

Personally I like the silver alloys on a darker car like FroGTI carbon Gray GTI but I want to reduce the silver look on my CW GTI. Any thoughts?
p.s. Having run with the wheels on this week there growing on me. I know there not to every ones taste but I like them as a winter wheel anyway!
