Pigments are coloured powders that do not dissolve in the liquid with which they are mixed. They have to be regularly mixed and ground in the (liquefied) binder. Properties of the paint such as colour, tinting strength, opacity/transparency and lightfastness are determined, among other things, by the type of pigment used.

a) Pigment insoluble
b) Dye soluble
