What gives our skin its shade (color)?

The color of our skin is primarily determined by the presence of melanin, a pigment produced by specialized cells called melanocytes. Melanin comes in different types, with eumelanin contributing to brown and black tones, while pheomelanin gives rise to red and yellow hues. Genetic factors influence the amount and type of melanin produced, resulting in the diverse range of skin tones seen in humans. Additionally, environmental factors such as sun exposure can also affect melanin production and skin color.
