Couleurs de Plantes Brazil Wood, Peachwood is a bushy and thorny shrub, common in the dry areas of Central America up to 1500 meters above sea level. The Central American redwoods were exported in the Middle Ages for use in dyeing, especially in Europe. Haematoxylum brasiletto is one of the richest in coloring molecules. The deep red color on wool and silk and good wash fastness makes it a preferred color in Europe at this time, but given its poor light fastness, this dye will be mainly used to shade red dyes of Madder (manual of recepies of Venetian dyers, 15 century). The Brasiletto is the 3rd most important source of red wood dye. Its export began in 1848 and its trade continued until the beginning of the 20th century.
