The main color giving component of natural brown ochre (ocher) is limonite which is not a single mineral but a mixture of several iron-containing minerals among them goethite, akageneite, lepidocrocite, and jarosite, goethite (iron oxide hydroxide α-FeOOH) being the main component.

Ochre (pronounced OAK-er) is clay pigmented by hematite, a reddish mineral that contains oxidized iron, which is iron that’s been mixed with oxygen, said Paul Pettitt, a professor of paleolithic archaeology at Durham University in the United Kingdom.
