Orange (heraldry)

In heraldry, orange is a tincture, rarely used other than in Catalan, South African, French municipal and American military heraldry. As a colour, Orange should be used against metals in order not to contravene the rule of tincture. Orange is distinct not only from Gules, but also from Tenné, which originated as the light-brownish colour of tanned leather, and from Carnation, used for the depiction of white human skin.
Orange was not allocated a pattern in the system of hatching developed in the early 17th century, but later received one in the form of a series of vertical lines of dots and dashes.
The orange colour used in heraldry should be rich and deep enough to be clearly distinguished from both metals, Argent and Or, and from Gules, Tenné and Carnation.
