Pigment names are often derived from their source. For example, the pigment that we call umber is named after Umbria, Italy.

Explanation:

Umbria is an Italian mountain region where this pigment is found and extracted. The name comes from the Italian terra d'ombra (Earth of Umbria). The umber is a natural brown or reddish-brown pigment that contains iron oxide and manganese oxide. It is darker than other similar terrestrial pigments, and in its natural form, it is called raw umber.
