Fustic (old fustic, yellowwood, Dyer's mulberry) is derived from a tall tropical hardwood (Chlorophora tinctoria) that grows wild throughout Central America, Mexico, the West Indies and Brazil. Fustic is high in tannic acid, which makes it a perfect cotton dye. It will also color silk and wool to luscious shades of burnt gold. This was the dye used to color khaki uniforms for the US Army in World War I.
Fustic dyes the clearest yellows with an alum mordant, and provides a good base for other colors: overdyed with indigo to yield forest greens and blue-greens; combined with madder and cochineal to make oranges; and mixed with logwood to produce olive greens.
