Description
Paint pigments prepared by grinding native iron containing minerals. Earth colors generally contain a mixture of iron oxides and other materials such as clay, chalk, and silica. The colors vary over the range from yellow, orange, red, brown, and black with each deposit having a unique color, composition, and working characteristics. Names for these colors include ocher, sienna, and umber. Earth colors have been used since prehistoric times and are permanent in all techniques.
