A week ago, I began a life drawing in charcoal on rough watercolour paper. It proved difficult to build the contrasts because the tooth grabbed the grains and prevented me lifting tones with putty. So I painted over it with gouache.
In retrospect, I needed to use more white in the mix or dilute the pure colours more. However, I liked the graininess of the charcoal showing though the paint. These next doodles were done later to explore these effects.
I was aiming for subtlety of colour, retaining the charcoal tones. I based the second pair of doodles on a photograph in a book on the siege of Stalingrad.
I went prepared to use this approach in life drawing yesterday. However, I followed instructions, painting the paper a mid tone to start, then building the picture with gouache white highlights then deeper grey dark tones before drawing into this with pastels and finally charcoal to give depth to the shadows. I didn’t have time to re-model her torso properly.
I’ve begun to make more self-conscious use of warm and cool colouring to suggest depth.
