Daniel Smith Luminescent watercolours, unlike anything ever seen in watercolour, simulate the glitter of a watery surface or the lustre of mother-of-pearl. They're made from mica pigment, thin transparent particles coated with highly reflective metal oxides. Pearlescent colours give white paper a pearl-like lustre. Use Pearlescent White as a slightly opaque glimmering glaze or combine with other colours to create sparkling pastel tones.
