Ochre

Ochre (/ˈoʊkər/ OH-kər; from Greek: ὠχρός, ōkhrós, (pale yellow, pale), also spelled ocher, see spelling differences) is a natural earth pigment containing hydrated iron oxide, which ranges in color from yellow to deep orange or brown. It is also the name of the colors 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".
