Brazilwood dye

== Description ==
A natural red dye produced from the hot water extraction of any of several tropical trees of the senna genus, Caesalpinia, such as C. brasiliensis (from Brazil), C. crista (from Pernambuco), C. echinata (peachwood from Nicaraugua), or C. sappan (sappanwood from East Indies and Asia). Brazilwood was used to dye textiles as early as the 12th century in Europe. Its principal colorant is brasilin, a hydroxyanthraquinone, that gives a deep red to brownish color when it is oxidized to form brasilein. Brazilwood produces purple shades with a chrome mordant and crimson shades with alum. When mordanted on chalk, brazilwood produces lakes ranging in colors from lavender to cherry to deep red. It was a cheaper red lake pigment than carmine. Brazilwood dye has been used for textile dyes, inks, paints, varnish tints, and wood stains. The color is not lightfast and fades when heated.
