Ochre
Definition:
(n.) A impure earthy ore of iron or a ferruginous clay, usually red (hematite) or yellow (limonite), -- used as a pigment in making paints, etc. The name is also applied to clays of other colors.
(n.) A metallic oxide occurring in earthy form; as, tungstic ocher or tungstite.
(n.) See Ocher.
