What is imprimatura painting?

With its roots in the great Italian artists, the term derives from an Italian phrase meaning 'first layer of paint'. When the drawing and painting technique is applied, it always comes as the first step. It is usually achieved using natural colors such as raw sienna or burnt umber, and almost always on white backgrounds. The transparent wash of color on the white painting background helps to tone down the brights.
