Ochre

Ochre is a color, usually described as golden-yellow or light yellow brown. As a painting pigment it exists in at least three forms:

• yellow ochre, Fe₂O₃ • H₂O, a hydrated Iron oxide
• red ochre, Fe₂O₃, obtained by heating yellow ochre
• brown ochre (Goethite), also partly hydrated Iron oxide
