I have the anthracite wheels on silver car combination, but they are 15x7 wheels. One problem is that it's very difficult to capture the color subtlety in a smartphone image. Here's what I got:
Closer but not so much of the car:
Main issue with a digital image is that the wheels look more like a metallic graphite from any kind of distance. There is some color in there, kind of a very slight tint of maybe a gray sage. The overall feeling is a charcoal/slate metallic color. But TD differentiates anthracite from graphite (which I do not think has metallic flakes, but I"m not sure). Ping Chalon and he can provide some examples.
