Natural dyes are colorants obtained from plants, invertebrates, insects, fungi or minerals. Most natural dyes are vegetable dyes, the main sources of which are various parts of plants such as roots, stems, seeds, barks, leaves and wood. There are also other biological sources such as fungi, snails, insects, etc. Natural sources were the main source of textile dyes before chemically dyeing. Our ancestors extracted and prepared dyes from these natural sources. Although, all the natural materials can’t produce color but there are some elements except plants that produce some expensive colors like sea snails, cochineal insects etc.
