Word Origin & History

umber
brown earthy pigment, 1568, from M.Fr. ombre (in terre d'ombre), or It. ombra (in terra di ombra), both from either L. umbra "shade, shadow" (see umbrage) or from Umbra, fem. of Umber "belonging to Umbria," region in central Italy from which the coloring matter first came.
Burnt umber, specially prepared and redder in color, is attested from c.1650.
