Another vote for silver, but I am biased.
These are 19" BBS CH-R in Brilliantsilber (Bright Silver). Supposedly, this finish from BBS is very complicated to create and involves several steps like a special silver base coat, then a powder coat, then a clear coat to achieve the final look. The end result is a beautiful, shimmering type of silver painted finish that creates a nice holographic effect with the words, "Motorsport" in the center of the wheel. Sadly, these details do not show up in the pictures.
