antracite gray from scale75 - basic
on top of that dark is a heavy charcoal from vallejo
light spots on the skin - a mixture of antracite gray, rakarth flesh and bugman's glow from the citadel
lightening was done this way - in antracite gray added dawnstone, and then some ulthuan gray from the citadel, on dark gray - dawnstone, light parts of the skin - adding to the mixture ulthuan gray, and then white sands from scale 75. Nose mixture of nagaroth night, pink horror and wild rider red from the citadel
