Hi all. I'm painting some GW ghouls but have run into a small problem I'm hoping someone can help me with. The skin colour I've chosen is a bleached bone base with sepia wash and purple glazing (to tone down the yellowness of bleached bone). The problem is that they are carrying various bones and skulls and I've done my bone painting with bleached bone for years and it looks too close to the skin colour. Can anyone recommend a colour recipe for bone that doesn't use Bleached Bone (or equivalent) as a base?

Thanks in advance.
