Our Luminescent watercolors, unlike anything ever seen in watercolor, simulate the glitter of a watery surface or the luster of mother-of-pearl. They're made from mica pigment, thin transparent particles coated with highly reflective metal oxides. Iridescent colors reflect light and their semi-transparent quality adds a fascinating sense of depth to your work. Iridescent Moonstone reflects in shades white and deep silver—a perfect choice for fish scales or moonlit water. Iridescent Moonstone shows up as a silvery-gray on white, but when applied over black becomes a glowing silver-white - like the reflection of the moon on a night-darkened sea.
