Analytical chemistry

Color, which contributes so much to the beauty of nature, is vital to the attraction and acceptability of most products used by modern society. As early as the 25th century BC, people used a limited range of natural colorants from both animal (e.g., cochineal) and vegetable (e.g., indigo, curcumin, alizarin, Tyrian purple) sources to color their surroundings and clothing. Dyes are substances that, once applied to a substrate, selectively reflect or transmit incident daylight. Most natural dyes are found in the roots, barks, leaves, bracts, flowers, skins, and shells of plants.
