Dye is a substance used to color materials. It is often used to color the fabric used to make clothing. It has low solubility. A pigment won't do this because it won't stick to the fibers of the fabric and color them. A dye can be natural, usually made from plant material such as berries, or a dye can be artificial, meaning that it is made by humans from chemicals such as petrochemicals.
Most natural dyes are gotten from different parts of a plant like the roots, fruits, bark, leaves, wood, fungi and lichens.[1] Most dyes are synthetic and are made from petrochemicals.[2]
Dyes can be classified based on their solubility and chemical properties.
