Andrea del Sarto
Grisaille ( or ; , from "gris" 'grey') is a painting executed entirely in shades of grey or of another neutral greyish colour. It is particularly used in large decorative schemes in imitation of sculpture. Many grisailles include a slightly wider colour range, like the Andrea del Sarto fresco illustrated. Paintings executed in brown are referred to as "brunaille", and paintings executed in green are called "verdaille".
