Camaïeu

When a picture is monochromatically rendered in gray, it is called grisaille; when in yellow, cirage.

This technique uses a buildup of white enamel to create highlights and light areas.

However, instead of using a black background, as in grisaille, transparent enamel is laid in first, beneath the whites.

Camaïeu can also refer, following the French usage, to chiaroscuro woodcut prints that imitate highlighted drawing on tinted paper.

This French word once was synonymous with cameo, but its meaning became restricted in the early eighteenth century.
