Now you need to establish a richness of color that will lay beneath your black hues. This is done by creating a glow. There are many reasons for this - too many to write here. You will have to trust me on this one: everywhere you see dark blacks or browns, you need to paint in a transparent yellow underlayer. Depending on the depth of the darkness - sometimes I paint three washes of transparent yellow to build up a good depth of color. Now you are ready to paint your black/dark brown hair.
