ABSTRACT
COLOR plays an important role in our daily life. Humans spend a lot of time selecting and matching colors, including choosing the color of their dress, colors with which to decorate their homes, car colors and food colors. In the animal kingdom, color plays an important role in warning other species and attracting the opposite sex. For example, the peacock male shows off a magnificent presentation of colorful feathers, which actually requires a substantial investment of metabolic energy. For ducks, the production of vibrant colors and impressive feathers is used to attract the opposite sex and indicate the health of the bird. In the plant kingdom, colors are used in a variety of ways to attract insects and birds to pollinate flowers. Also, in this case, creating such colors requires a fair amount of energy from the plant’s nutritional reserve, but it is important to sustain the specie.
