Melanin is the pigment primarily responsible for skin color. Through a process called melanogenesis, cells called melanocytes produce melanin, which is found in the skin, eyes and hair. The subcutaneous layer of the epidermis produces a dark pigment in the skin known as melanin.
Melanocytes synthesize and store brown pigment, melanin, that gives the tissue a dark color. Melanocytes are common in the stratum basale of the epidermis in the skin, where they play a major role in determining skin color. They are also found in the dermis, eye, heart, brain, and bone..
Melanocytes, which produce melanin, are found in the basal layer of the epidermis, also called the stratum basale.
Melanocytes produce two chemically distinct types of melanin pigments. They are pheomelanin, which is yellowish-red, and eumelanin which is a black-brown.

Eye colour can change with exposure to the sun. Sunlight stimulates melanin production in the eye which results in a change of colour.
it is melanocyte stimulated hormone
Melanin gives color to the skin, hair, and iris of the eyes. Levels of melanin depend on race and amount of sunlight exposure. Sun exposure increases melanin production - to protect the skin against harmful ultraviolet rays. In addition, hormonal changes can affect melanin production.
Exposure to ultraviolet B radiation increases the production of melanin.

Production of melanin in the skin decreases; so does production of vitamin D.
Thyroid stimulating hormone, or TSH, stimulates the production of triiodothyronine and thyroxine. TSH comes from the pituitary gland.
High levels of the hormone oestrogen stimulates the production of FSH hormone in women.
