what is Humbrol Track Color?

Now I got ya (replied in Armor as well).

Track color is the red-brown of the 6-Color DCUs (Chocolate Chips).  The darker brown is just that, a dark brown.  I use a leather or chocolate color for it.  

Khaki Drill is a khaki with hint of green color.  It is the color of Brit WWII tropical uniforms.

I use Testors Model Master SAC Bomber Tan for it.

Thanks so much Gino and thanks for the pic of the Khaki Drill. Not having a clue I had no idea what it was, and the IPMS Stockholm did not have a good match, other than XF49 Tamiya Khaki (*may be correct, donno) but no other match.

I figured I may be able to use Leather for that deeper red/ brown.

 Sorry for the incorrect pattern, I got my terminology cofuzzled (never wore 'em! LOL, got out too soon!)

 Have a good one!
