One of the projects we had to do at school before starting on Limited Palette, was a cast study of warm and cool light. At first glance, this appears to be a black and white painting, but if you look closer, you will see warm orangy tones in it. Done with an extremely limited palette of burnt sienna, Ultramarine Blue, Naples Yellow and flake white (no black), my job was to paint as accurately as I could, the values and the relative temperature changes I saw in the cast. The project took about a month or two and marked the end of my mostly monochromatic months at the atelier.
