Clay earth pigment

From Wikipedia, the free encyclopedia

Clay earth pigments are naturally occurring minerals that have been used since prehistoric times as pigments. The primary types are

• ochre
• sienna
• umber

Earth pigments are known for their fast drying time in oil painting, relative inexpensiveness, and lightfastness. Caveman paintings done in sienna still survive today.
