Color and opacity, the important aesthetic attributes of paint, are given by incorporation of pigments. Pigments impart color by selective absorption of visible light, while opacity is obtained by scattering and/or absorption of visible light by pigment particles. Pigments may also affect texture-related appearance characteristics of coatings, such as gloss and sheen. Various special-effects coatings can also be formulated by special types of pigments discussed in Section 3.3.8.
