Clay earth pigment

Clay earth pigments are naturally occurring minerals, principally iron oxides, that have been used since prehistoric times as pigments.

Description

The primary types are:

• Ochre
• Sienna
• Umber

Earth pigments are known for their fast drying time in oil painting, relative inexpensiveness, and lightfastness.

Cave paintings done in sienna still survive today.
