This color was a long time in coming. Made from a pigment that is no longer available it has the most amazing properties producing a brown that has a very subtle shimmer. These are artist grade archival watercolors. Each pan is hand poured using our own recipes for limited edition colors. We use a natural watercolor binding medium using the sap of acacia trees and the honey from its blossoms. The addition of a natural preservative (NOT CLOVE OIL), distilled water and food grade glycerine assures that these colors will react immediately to the touch of a wet brush.
