Ochre ( /ˈoʊkər/ OH-kər; from Greek: ὠχρός, ōkhrós, pale) is the term for both a golden-yellow or light yellow brown color and for a form of earth pigment which produces the color. The pigment can also be used to create a reddish tint known as "red ochre". The more rarely used terms "purple ochre" and "brown ochre" also exist for variant hues. Because of these other hues, the color ochre is sometimes referred to as "yellow ochre" or "gold ochre".
Ochres are among the earliest pigments used by mankind, derived from naturally tinted clay containing mineral oxides. Chemically, it is hydrated iron (III) oxide, mineralogically known as limonite. Modern artists' pigments continue to use the terms "yellow ochre" and "red ochre" for specific hues.
Ochre clays have been used medicinally from the earliest times. For example, such use is described in the Ebers Papyrus from Egypt, dating to about 1550 BC.
Ochres are non-toxic, and can be used to make an oil paint that dries quickly and covers surfaces thoroughly. To manufacture ground ochre, ochre clay is first mined from the ground. It is then washed in order to separate sand from ochre, which can be done by hand. The remaining ochre is then dried in the sun and sometimes burned to enhance the natural color.
