Melanin.
Hormones have nothing to do with human skin color. Melanin, a pigment, determines skin color by the amount of it present in the skin. The more melanin, the darker the skin.
Melanogenisis is the activity that controls melanocytes. Melanocytes are the cells in the human body that produce melanin, the pigmentation found in eyes and skin.

A persons pigment called melanin gives the skin and hair it's color. In hair melanin is found in the cortex which is the hair second layer. Genes in a human body determines the number of melanocytes in the hair and the type of melanin it produces. The size and type of melanosomes will determine the natural color of the hair. There are two types of melanin, eumelanin(brown/black) and pheomelanin (red).
Melanin is a pigment in the skin of animals (including humans). Melanin is essentially what allows the human body (the skin) to darken when sunlight (or, ultraviolet rays) hits it. The skin absorbs the UV rays and the melanin allows the skin to become darker. A simpler definition: Any of a group of naturally occurring dark pigments, especially the pigment found in skin, hair, fur, and feathers.
