The iridescent series produces colors similar to a rainbow, such as gold, red, purple, blue, and green, through the precise control of the coating thickness of titanium dioxide, and gives it a luster. The colors of this series of products are entirely due to physical light interference phenomena.

The optical path difference between the reflected light of high refractive index titanium dioxide and the reflected light of low refractive index mica interferes and presents different colors. It does not contain any pigments, but has a strong color concentration. In addition, the titanium dioxide crystal form of this series of products is all rutile type, which has good stability, no fading, no color migration, and also has good weather resistance. This series of products also produce rich and vibrant pearl effects during use due to different base colors or color matching with organic pigments.
