Duochrome Emerald is the slightly reflective green of tender new shoots or buds in the Spring. Many living things have a slightly luminous quality to them that cannot quite be painted in regular watercolors. Daniel Smith Luminescent watercolors, unlike anything ever seen in watercolor, simulate the luster of a bird's feather, the iridescence a butterfly or insect, the luminous quality of flowers and leaves. They're made from mica pigment, thin transparent particles coated with highly reflective metal oxides. Duochrome Emerald shifts between two different shades of green-a lovely emerald and a very slightly reflective green-gold. All the Daniel Smith Luminous watercolors mix well with other colors and lend their luminosity in proportion to the mix. Mixing Luminous watercolors with other colors is an ideal way to use them!
