After having completed the wet white layer and allowing it to dry thoroughly I re-rendered the features of the face in a Raw Umber, this time without using any white at all. In this layer I’m only interested in capturing areas of deep shadow or dark colour. There’s a dramatic difference between the greys that this paint make when mixed with white, and the warmer tones that it gives when used alone. This needs to dry thoroughly, then I’ll take another look to see what needs to be fixed, then move on to painting flesh over the grey layers.
