Some ideas. Cayman green, shades with added black and brown (smokey ink even) highlights with added khaki and bleached bone. Cayman green can be replaced with yellow olive as well for a slightly darker and \"colder\" green. For a bit more vibrant green add a... vibrant green to the mix
Well, the most exotic Orc skin recipe I ever used: start with black, then gradually add Camo Green (GW) to the black, till you got almost pure camo. Then maybe add some Rotting flesh to the Camo for final highlights... like here:
I\'d say look around on the rackham site, you\'ll spote some exotique skin colors
Allan also does some nice skin colors and I belive he has the recipies on his site, might be worth a look. Won\'t be in VGC though.
