Prehistoric pigments | Resource | RSC Education

Palaeolithic artists seem to have used two main colours although others have been found in some cave art. The dominant two are red (which tends to be iron oxide: natural hematite or heated goethite) and black (charcoal or manganese oxides). These colours were natural materials and are known as 'pigments'.
