They are an essential tool in any art class! The Pitt Monochrome chalks are an important tool in life drawing courses. The most popular colours are black, white, red chalk and sepia, as they add vitality, life and expression to drawings. Pitt Monochrome chalks also hark back to an old tradition of figure drawings from the renaissance, which is why the chalks used for drawing are harder than conventional pastel chalks. The colours are lightened in the traditional way with white and the shades are darkened with black.
This means that the lines do not disappear completely when the colour is smudged. The red chalk and sepia chalks are combined with grease-free and oil-based drawing pencils for details and lines.
