Inheraldry,orange is atincture, rarely used other than inCatalan,South African, French municipal andAmerican military heraldry. As acolour, Orange should be used againstmetals in order not to contravene therule of tincture. Orange is distinct not only fromGules (red), but also fromTenné (orTanné), which originated as the light-brownish colour of tanned leather, and fromCarnation, used for the depiction ofwhite human skin.
Orange was not allocated a pattern in the system ofhatching developed in the early 17th century, but later received one in the form of a series of vertical lines of dots and dashes (a hybrid of the vertical lines used to represent Gules, and the dots used to representOr).[1]
The orange colour used in heraldry should be rich and deep enough to be clearly distinguished from both metals,Argent (white) andOr (yellow), and fromGules (red),Tenné (light brown) andCarnation (flesh-colour).
