Classification Of Natural Dyes

Natural Dyes are derived from plants, animals and minerals. The process of making Natural Dyes typically involves crushing, grinding and steeping of the resource in water to extract the colorant from it. The colorant so obtained is further treated to make Natural Dye. Depending on their source of origin, Natural Dyes can broadly be classified into two categories, both of which are discussed briefly in the following section.
