Pearlescent pigments have what we call mica. These are tiny reflective metal or refractive mica pigments that are added to the coating as well as several other elements. When light hits it, the coatings acts kind of like glitter you used as a kid. When the light hits the surface, it scatters the light in many directions. This creates the unique pearlescent effect. Valspar is seeing a lot more of these coatings used today to differentiate projects.
