Sienna (from Italian: terra di Siena, meaning "Earth of Siena") is an earth pigment containing iron oxide and manganese oxide. In its natural state, it is yellowish brown, and it is called raw sienna. When heated, it becomes a reddish brown, and it is called burnt sienna.[1] It takes its name from the city-state of Siena, where it was produced during the Renaissance.[2] Along with ochre and umber, it was one of the first pigments to be used by humans, and is found in many cave paintings. Since the Renaissance, it has been one of the brown pigments most widely used by artists.
The first recorded use of sienna as a color name in English was in 1760.[3]
The normalized color coordinates for sienna are identical to kobe, first recorded as a color name in English in 1924.[4]
