Topic - Viridian

Viridian is a blue-green pigment, a hydrated chromium(III) oxide, of medium saturation and relatively dark in value. It is composed more of green than blue. Specifically, it is a dark shade of spring green, the color between green and cyan on the color wheel, or, in paint, a tertiary blue–green color. Viridian takes its name from the Latin viridis, meaning "green". - Source: Wikipedia
