People with lightest skin live in northern Europe. These are Nordic. Those, whose skin is darkest, inhabit West Africa. The population of South Asia is characterized by a grim – yellow skin. However, most of the inhabitants of our planet are neither white nor black, or yellow skin, but countless shades between light and dark.

What causes the color of skin, hair and eyes in humans? The reasons lie in numerous chemical processes that take place in our body. The skin contains certain basics of color, called chromogenics, which are actually colorless. When certain enzymes act on this basis for color, result is a certain color.

Without the presence of substances that give color, the skin is grayish-white. The color of human skin depends on three substances or colored pigments contained in human body. The first of these substances is melanin. It is brown. The second is the carotene, a substance that has a yellow color. The third is called hemoglobin and is a red colored substance found in the blood.
