Ochre
Ochre is a naturally occurring clay rich in iron as it is a mixture of ferric oxide and various other clay and sand components. It is a naturally occurring pigment; its color can range from red, brown, orange to even yellow. Ochres have been used for wall paintings since prehistoric times. Ochres are non-toxic in nature and are used to produce oil paints that dry quickly. Synthetic iron oxides are used to manufacture modern ochre pigments.
