Oil paint
Pigment
The color of oil paint is derived from small particles of colored pigments mixed with the carrier, the oil. Common pigment types include mineral salts such as white oxides: zinc oxide, titanium dioxide, and the red to yellow cadmium pigments. Another class consists of earth types such as sienna or umber. Still another group of pigments comes from living organisms, such as madder root. Synthetic organic pigments are also now available. Natural pigments have the advantage of being well understood through centuries of use, but synthetics have greatly increased the spectrum of available colors, and many have attained a high level of lightfastness.
