Skin is the largest organ of the body and consists of two layers namely epidermis (the upper layer) and dermis (the lower layer). The lowermost layer of the epidermis is referred to as the basal layer which contains 'melanin', the cells responsible for skin color. The vascularity and the thickness of epidermis also affect the color of the skin.
