So for those interested, I had the wheels redone my Nu-Tec in Anaheim. The powder color is Anthracite and it is the PERFECT gunmetal IMHO. It is light enough to contract with the tires but dark enough to offset a light color car. Unbelievable finish too...super lacquered look. I'll post pics when the sun comes out again.
