In addition to the conventional inorganic pigments, there are several other special classes of non-conventional inorganic pigments for producing energy - efficient colored paints. The most important technology in the production of cool paints is the formulation with complex inorganic colored pigments (CICPs) or mixed metal oxide (MMO) pigments [6].This special group of non conventional pigments presents spinel structure and is known for its highly visible opacity [5] and high reflectance in NIR radiation.These pigments also present a long service life in normal environments, are heat stable and chemically inert.
