In this video I used 3 colors to for the skin. This girl I found on google images (which I can find no reference to where she came from) I am using her as a portrait subject. I outlined her face using titanium white. Then for her base I used titanium white, burnt umber and yellow orche or a mixture of these three. To add shadow I usually use color of some sort. The colors I choose were cadmium red, teal, hansa yellow, I paint intuitively as I have no plan. Hence my paintings may have turquoise lips or orange hair. I randomly pick up colors and have no rules to how to do things. I Outline the face with colors such as quinacridone magenta using my fingers to smudge the lines.
