dye and dyestuff
- A dye is a colorant or pigment that dissolves completely, and is translucent. Textile fibers and fabrics are typically dyed in vats of the stuff. Because dyes are mixed with liquids just before their use, commercially produced dyes are highly concentrated. Natural dyes have been derived from a wide range of plant and animal sources, and are sometimes referred to as dyestuff. Dyes color by penetrating substances, in contrast to drawing and painting colors, which must simply adhere to surfaces. There are many types of dyes, varying in their effects, the means of their use, and permanence.
