Narrator: Today's word is "Raw-Umber" — noun, pronounced /ˌrɔː ˈʌmbə/, with the stress on "um".
Narrator: Raw umber is a cool, slightly greenish dark brown earth pigment, containing iron and manganese oxides, used without heating.
Narrator: In plain English, raw umber is a muted, earthy brown, cooler and greener than burnt umber.
Narrator: Umber probably comes from the Italian terra d'ombra, earth of shadow, or from Umbria, a region of Italy, so its origin is uncertain. Raw means it has not been roasted, and roasting turns it into the warmer burnt umber.
Narrator: "Toning a canvas with raw umber" describes painting a thin brown layer before starting a picture.
