Cutch is an important historical brown dye that comes from the heartwood of the cutch tree (Acacia catechu). This colour was produced by steeping the wood into hot water until a syrupy liquid immerses. It has high light fastness and wash fastness as well as being inexpensive. Cutch is a very rich source of tannins and excellent dye for cottons, it is also suitable for dyeing wool, silk, and cotton a yellowish- brown.
