History

This pigment gets its name from the Latin word umbra, meaning shadow or shade. Its full name is listed as terra d’ombra, meaning earth of shadow/shade, due to its original extraction from the area of Umbria, Italy. It has been used as a pigment since prehistoric times. Currently, the finest umber comes from Cyprus.
