Colorants are used in many industrial applications such as to color ceramics, photographs, plastics, prints, paints, and clothes. The word colorant holds the whole range of coloring materials such as dyes and pigments, and others. While both dyes and pigments are types of colorants, they are different from one another, such as pigments are subdivisions of color which can be insoluble in oils, water, and resins and used for coloring inks, cosmetics, paints, and plastics. Whereas, dyes also known as dyestuffs, are usually water soluble, and highly used in coloring of paper, textiles, and other substances. Furthermore, the source of all types of colorants such as dyes, pigments, coatings, master batches, inks, paint, and others, is either organic or inorganic.
