The term for the color of our skin and hair is pigmentation. Pigmentation refers to the presence of pigments, primarily melanin, which determines the color of various tissues in the body, including the skin, hair, and eyes. Melanin is produced by specialized cells called melanocytes, and its levels and types influence whether a person has lighter or darker skin. Additionally, pigments in hair can also change with age or exposure to the sun. Variations in pigmentation contribute not only to aesthetics but also to an individual's adaptation to environmental factors, such as UV radiation.
