Our Daniel Smith Extra Fine 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. When applied, they create a sense of depth and a sheen that changes with the angle of reflection and observation, sometimes reflecting their complementary colors. The Interference and the Pearlescent colors appear virtually colorless when applied to white paper but when applied over a dark color they transmit gleaming color. The Iridescent colors reflect light, have stronger color and are semi-transparent. We offer three sets, an Interference Set, Pearlescent/Iridescent Set and an Iridescent Antique set. The 7-color 15ml tube Pearlescent/Iridescent Set includes: Pearlescent Shimmer, Pearlescent White, Iridescent Bronze, Iridescent Copper, Iridescent Gold, Iridescent Russet and Iridescent Scarab Red.
