The optical absorption of organic and inorganic pigments and optical reflectance compared to metallic pigments and Pearlescent pigment color is entirely different, so its effect is unique. Pearlescent pigments is a full three feet above the main representatives of optical interference pigments.
Pearlescent pigments with the particles vary in size and in use showed different results. All in all, particles larger Flash effect is stronger, and less coverage of the background otherwise smaller particles, covering more of the background, more soft luster.
Change the thickness of the metal oxide or metal oxide type will have color variations
