"A natural brown clay earth pigment that contains iron and manganese oxides, silica, alumina, and lime; tending to be less orange-red than sienna. The term refers to the region of Umbria, Italy, although the pigment is found elsewhere in the world, notably on Cyprus. It has been used as a pigment since prehistoric times."@en
