Pigmentation is the process by which an organism produces color in its tissues or cells. This can refer to the color of skin, hair, eyes, or other parts of the body. Pigmentation is influenced by genetics, environmental factors, and exposure to sunlight. Research in pigmentation includes studying the genes and pathways involved in producing color, understanding the evolution and adaptation of pigmentation in different species, and investigating conditions such as albinism or melanoma that affect pigmentation. Additionally, research in pigmentation has important implications for understanding human diversity, health, and disease.
