You can paint them either a black or a very dark grey.  They did accumulate dirt, snow, mud, etc.  The contact part you'll want to highlight with a metallic steel or with a #2 pencil where the track pad makes contact with the ground and the metal is exposed giving it a metallic sheen on that part.

Rob;

Thank you very much.

best bet is an earth brown color with some highlights. Take a look at bulldozers on construction sites; the tracks tend to take on an earth color with some metallic highlights.
