Why Do We Have Different Skin Color?

We often wonder why we and all around us differ so much when it comes to skin color. The color of the human skin varies almost from light translucent to almost black. All these wide varied colors that we human being have come from a particular pigment known as melanin. The type and amount of melanin present in an individual's body defines his or her color.

The color of every individual is more or less affected by the presence of four pigments in the body - melanin, oxygenated hemoglobin, reduced hemoglobin and carotene. However melanin stands out as the most powerful of all and gives us the color that we have. Melanin pigment are produced by special cells known as melanocytes which are found in the epidermis of our skin. Genes control the production of melanin cells in an individual body. The melanin producing cells in every adult ranges from 60,000 in each square inch of the skin. Few melanocytes mean less pigment which means lighter skin. Hence we have different skin color depending upon the production of melanin.

Besides melanin one more factor that affects one's skin color is haemoglobin. Haemoglobin combines with oxygen to produce the rosy complexion which is often referred as a sign of good health. Reduced haemoglobin causes anemia which makes a person appear pale.
