Melanin is responsible for determining the color of skin in humans. Keratin levels, sweat gland activity, and sebum production may influence the overall appearance and health of skin, but they do not play a direct role in determining its color. Melanin is produced by specialized cells known as melanocytes, which are located in the epidermis, or the outermost layer of skin. When these cells produce more melanin, the skin appears darker, while less melanin production results in lighter skin tones. The amount of melanin in the skin can also be affected by factors like genetics and exposure to sunlight. Therefore, the color of skin is primarily dependent on melanin and the amount of blood supply present in the skin.
