Description

A natural yellow organic colorant that, in addition to Quercitron, is obtained from oak bark. Pure flavine produces a vivid yellow on wool when mordanted with alum and tin. Flavine naturally mixed with quercitron from oak extracts produces a wider range of colors from a greenish yellow to orange to a dark green. Flavine, used both as a dye and lake pigment, is not lightfast.
