Pigments are used to colour paint, ink, plastic, textiles, cosmetics, food, and other things. Dry dyes that are often powdered into a fine powder make up the majority of the Dyes, Pigments, Paints, and Coatings used in production and the visual arts. The binder (or vehicle), a largely neutral or colourless substance that suspends the pigment and gives the paint adherence, is applied to the powder to be used in paint. A pigment that is insoluble in its vehicle (resulting in a suspension) is often distinguished from a colourant that is either liquid in itself or soluble in its carrier (resulting in a solution).
A colourant can function as either a pigment or a dye, depending on the medium.The formation of a pigment from a colourant can be accomplished by precipitating a soluble dye with a metallic salt. Lake pigment is the name given to the pigment that causes the same. No matter how soluble they are, all coloured substances are referred to as biological pigments. Both in the arts and in practical applications, permanence and durability are valued qualities. Dyes, Pigments, Paints, and Coatings that are not permanent are referred to as fugitives. Fugitive pigments fade with time or exposure to light, while some gradually turn black.
