These figure paintings were done with the dead palette which was used by the dutch masters. It is the most ideal palette for the human form as is permits a wide range of values and flesh tones from just a few basic paints. A 10 value scale string is mixed for black&white, reds and yellows. Each string is lined up parellel to each other and the artist can mix only within a vertical range, i.e. yellow 1 cannot be mixed with red 2 or black 3, etc. The two most prominent paints used will be Yellow Ochre and English Red. There is quite a bit of intitial setup to mix the palette properly, but once the artist has it done, remixing at the proper value and color becomes second nature.
