Watercolour Paints

Watercolour Paints comprise four principal ingredients:

colorant, commonly pigment (an insoluble inorganic compound or metal oxide crystal, or an organic dye fused to an insoluble metal oxide crystal);

binder, the substance that holds the pigment in suspension and fixes the pigment to the painting surface;

additives, substances that alter the viscosity, hiding, durability or color of the pigment and vehicle mixture; and

solvent, the substance used to thin or dilute the paint for application and that evaporates when the paint hardens or dries.
