Which pigment gives skin its color?

Explanation:
Melanin is the pigment that gives skin its color. It’s produced by melanocytes in the epidermis and then distributed to surrounding skin cells. The amount and distribution of melanin determine how light or dark the skin appears, and this varies with genetics and sun exposure. Melanin also helps protect skin from UV radiation by absorbing harmful rays. Keratin is a structural protein that strengthens skin, hair, and nails, not color. Collagen provides structural support and elasticity in connective tissue, not pigmentation. Sebum is an oily secretion from sebaceous glands that keeps skin moisturized, not color.
