Which type of tracks, there are several? You probably have the T-51 Rubber block tracks. These are painted black on the blocks with gun metal or similar color on the outside links. The track links should be worn a little, and dry brushed with steel. If you have another type of tracks lets us know and we can further help you. The "wheels" are normally the same color as the take, slightly more worn, with black (toned down a little) rubber along the outside.
