|The finished painting|
Monochrome underpainting in burnt umber I pay attention to the general placement of the head and the relation of the various features
Adding color I observe the colors on the face: it's a cool color scheme. I paint patches of colors and not objects. Basic color mix: burnt umber, alizarin crimson, white. Light: I add orange and white. Darks: I add ultramarine and more burnt umber. I grey out when needed with a mix of black, white and ochre or use a premixed medium gray.
