I have a 300C with the interior color "Dark Slate / Light Graystone" (this is the light tan colored seats and carpet). I'd like to order a floor mat from US Speed, but I can't seem to find which color is a factory match. The nice people at US Speed sent me some carpet samples, but none of them were close to my car. Here are the colors available for the 300C from their web site:

Has anyone with this interior color ordered the mats from them? Which color did you get?
