The dyes that we sell are termed the exotic or historic natural dyes. They yield a good to excellent wash and light fastness when used in proper combination with mordants. We use them in our own studio and in our naturally dyed clothing.
A full palette of colors can be achieved by varying the mordants used and by blending dyes together (such as cutch and cochineal, or cochineal and madder, or madder and logwood). Overdying with indigo can make greens from osage or burgundies from madder. Some dyes are available in a very concentrated extract form.
