Does any one now what colors to use for Bossk skin?

I used the Aggaros Dunes contrast paint for mine, over the Wrathbone primer and that seemed to work well.

The original suit had a brown tinge, but clone wars he had a more greenish tinge.

I used Vallejo Flat Earth mixed with Tan Earth, at about 2:1. Used Tan Earth and Dark Sand for highlights on the scales. The claws I used the base skin color with a little US Olive Drab mixed in for an even darker look.

Washed with Agrax Earthshade.
