Almost every art academy features monochrome colors such as black, white, red chalk, and sepia in their life drawing courses. These colors add vitality, liveliness, and expressiveness to the drawings.

PITT Monochrome chalks embrace this traditional approach to figurative drawing, which is why the chalks are harder for drawing applications compared to regular pastel chalks. When blending the colors, the lines do not completely dissolve. The red chalk and sepia chalk are complemented by both oil-free and oil-based drawing pencils for details and lines.
