natural, synthetic color pigments

natural, synthetic color pigments
Artist colors are made using pigments. Some pigments are found in the nature and they are called as Natural pigments
Pigments can also be prepared in lab and are known as Synthetic pigments. Paints based on Synthetic pigments, on thier labels, may have "hue" as prefix.

Single pigment color and multi pigment color
Single pigment colors are made out of one pigment.
Multi pigment colors are mixture of more than one pigment.
Colors produced this way may not be as brilliant as Single pigment colors.
Ex: Alizarin Crimson is a mixture of Quinacradone Violet and Naphtol Red. Quinacradone Violet has blue bias and Naphtol Red has orange bias When we mix Alizarin crimson with someother color; we may get unexpected colors because of orange bias and blue bias of original colors.
