Ochre

Earth pigment of characteristic colour

Ochre ( OH-kər; from Ancient Greek ὤχρα (ṓkhra) from ὠχρός (ōkhrós) 'pale') is a family of natural clay earth pigments, made up of ferric oxide and varying amounts of clay and sand, ranging in colour from yellow to deep orange or brown. The term is also used for the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as red ochre (or, in some dialects in England, ruddle).
