Fustic (Chlorophora tinctoria or Maclura tinctoria) is a tall tropical hardwood that grows from Mexico to Argentina. Fustic is high in tannic acid, which makes it an ideal cotton dye. In fact, it was used in the military to dye the color khaki during World War I.

On cotton, it will dye a clear gold and on silk and wool it will dye gold to brown-gold. Fustic also provides a good base for other colors: indigo overdyed with fustic creates an khaki green; combined with madder and cochineal to make oranges; and mixed with logwood or with iron to produce olive greens.

Use it at 10% on the weight of fiber (WOF) for bright rich gold with a strong exhaust dyebath for additional color. Lower percentages will produce a lemony shade. The high tannin content of this dye will result in a slight color shift toward a golden buff when exposed to direct sunlight.
