The monochrome colors black, white, sanguine, and sepia are found in life drawing classes at almost every art school. They bring images to life with vitality and expression. This is an old tradition of figure drawing that dates back to the Renaissance, enhanced with white and deepened with black shadows. Faber-Castell's Pitt Monochrome pencils connect to this long tradition of figure drawing, which is why the pencils used for sketching are harder than conventional pastel pencils. For this reason, the lines do not completely disappear when smudged. The sanguine and sepia pencils are complemented by oil-free and oil-based drawing pens for sketches and details.
