The Amuse 370z is running CE28s; I believe the color is Ti silver. Their cars look great with this color. It's been the same color and wheel on most of their demos cars including the Touge Monster S2000, GT1 Widebody S2000, and Z33.
Chris, check out this link. Colin took some pictures of the yellow Amuse Vestito when we visited Amuse earlier this year. I think it would look great in black; not a fan of the yellow.
