Used to paint sepulchral guard, but should apply to any generic skeletons.

1. Undercoat - cover with dark green blue similar to Deep Ocean Blue (I mixed my own using molotow as that's what I have, but was aiming for an Dark Sea Blue kinda colour) hit with a zenethol with an off white (I used molotow natural white, not on the apps range but any boney off white will do.) dry brush edges lightly with Bold Titanium White
2. Bone - basecoat Monster Brown avoid blue shadows, highlight Iraqi Sand wet blend some of the blue you primed with into the shadows. wash with Pallid Bone or Skeleton Horde highlight with Off White and blend with what ever method suits you, I wet blended with my wash. Hit your shadows with a very watered down version of your dark prime from the airbrush in the shadows.
