[[Why is the color of human skin white or black? Our skin contains special cells called melanocytes, which produce a pigment called melanin. This melanin determines the color of the skin, ie the skin color is white or black mainly due to the presence of this melanin on the skin. The more melanin in the body, the blacker it is. Melanin levels again depend on ethnicity, heredity, and the presence of sunlight. As the production of melanin increases, the color of the skin becomes darker or blacker, as is the case [with sunburn](https://howtodiscuss.com/t/how-many-seasons-of-hunter-x-hunter-are-t here/34067)
