Cannibals of the wasteland

Just finished a warband for wastelands 3.0, 18 man unit of cannibal savages. These are from khurasan,basically painting whatever I find first when retrieving things from storage. Really fun figs to paint up...I think they look better with vaguely flesh colored skin instead of greenish. Why is the default for mutants always a greenish tint? Reminds me, I have some 2nd ed. Orcs I painted grey instead of green. At least now I have an opponent for some wastelands gaming, now I have two factions, robots,and cannibal savages. Next up is a squad of human stalker/explorers.
