Camaïeu

Technique that employs two or three tints of a single color, other than gray, to create a monochromatic image

Camaïeu (also called en camaïeu) is a technique that employs two or three tints of a single color, other than gray, to create a monochromatic image without regard to local or realistic color. When a picture is monochromatically rendered in gray, it is called grisaille; when in yellow, cirage.
