Non-orange Traffic Drums?

Traffic drums are almost always orange.  You see them on the side of the road, on the highway, the freeway, in your town.  I have personally never seen traffic drums that are not orange, but they are out there.

Black traffic drums are more common in areas that are colder, they can be used as marking devices in snowy areas.  The problem is that traffic drums need to be bought in quantities around 5000 (usually) in order to change the drum color.
