    • n umber A natural pigment somewhat resembling an ocher, but darker and browner, due to the presence of oxid of manganese. It probably originally came from Umbria in Italy, but now the best varieties come from Cyprus. The natural earth is called raw umber. When it is heated to almost a red heat in a furnace, the brown hydrated oxid of iron is changed into the red oxid of iron, and the pigment becomes redder and deeper in color, and is called burnt umber. Both these umbers are very important colors, both for artists and in house-painting. They are permanent, pure in tone, and of great service in making various tints.
