  Solution
Melanin is produced by cells called melanocytes. Skin color is due to the presence of melanin, which is controlled by 6 genes.There are two forms of melanin pheomelanin and eumelanin. Pheomelanin is red to yellow in color, and eumelanin dark brown to black. Light complexion skin people produce more pheomelanin and those with dark colored skin mostly produce eumelanin.
The more melanin the skin makes, the more darker the skin color goes. So the more melanin results in brown shade and the skin tone gets brown.
