A Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answered. Melanocytes are the cells that are responsible for producing the pigment melanin, which gives color to skin and hair. Everyone has melanocytes, but people with dark skin produce more melanin than those with lighter skin do.
Skin color is due primarily to the presence of a pigment called melanin, which is controlled by at least 6 genes. Both light and dark complexioned people have melanin.However, two forms are produced--pheomelanin, which is red to yellow in color, and eumelanin, which is dark brown to black.elanin is normally located in the epidermis, or outer skin layer. It is produced at the base of the epidermis by specialized cells called melanocytes. These cells have photosensitive receptors, similar to those in the eye, that detect ultraviolet radiation from the sun and other sources.
