It is black as they all are and made of a flexible rubber-like material. If you have seen the lip spoiler before you would know what im talking about. Here is a picture of it on my car a few months ago just to give you an idea- http://anarch13.tripod.com/rais/colt/max2.jpg
Dont confuse the lip spoiler with the luggage rack, they are totally seperate.

Here is a good picture from wings west of their replica:

Btw, the wings west replica which is identical costs $225 believe it or not.
