Concept Much of my colored pencil drawing in recent years has been on mediumvalue colored papers such as browns, greys, and lavender. On medium-value paper, I can work with both light and dark pencils. It is exciting to see the effect of the light colors and whites contrasting on the dark papers. The dark papers also make it easier to achieve strong darks. This is a time-honored, traditional technique. Masters of drawing such as Leonardo da Vinci have worked on medium-value toned papers since the Renaissance. .
