Highly pigmented and finely ground watercolors made by hand in the USA. Extra fine watercolors produce clean washes even layers and also possess superior lightfastness properties. 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 Goldstone is a rich gold with a slight reddish undertone.
