Tinting Strength

Two pigments may look alike but their tinting strengths can differ greatly. This is by no means always the fault of extenders, but may also depend on the particle size or the manner of grinding. In aqueous techniques, especially in watercolor, wetting agents can significantly improve the tinting strength of a pigment. It is im possible to judge readymade paints by their appearance only, and yet this is what painters usually do. The tinting power of a pigment can only be a matter of economics but, in techniques like sgraffito, is of vital technical importance for the cohesion of the colored mortar. {see also Graffito Techniques...] [p. 64]
