Melanocyte-stimulating hormone is a collective name for a group of peptide hormones produced by the skin, pituitary gland and hypothalamus. In response to ultraviolet (UV) radiation its production by the skin and pituitary is enhanced, and this plays a key role in producing colored pigmentation found in the skin, hair and eyes.
Skin color is determined primarily by the amount and type of melanin, the pigment in the skin. Variation in skin color is largely due to genetics. As a general pattern people with ancestors from tropical regions and higher altitudes (hence greater UV light exposure) have darker skin than people with ancestors from subtropical regions. Other less important factors may include sun exposure, disease (such as jaundice or Addison's disease), food intake (e.g. excess beta carotene in your diet), hormones (e.g. darkening of skin during pregnancy called chloasma), or autoimmune conditions such as vitiligo.
It mostly depends on your parents' skin color and the area your family lives in.
Your parents' genes will be passed down to you. The dominant allele with come through more than the other.
Also, the farther you live from the equator, the paler your skin is because of lack of sun's strength.
The relative number of melanocytes and melanin produced per unit of skin.
Melanin is responsible for skin color.
It is the protein that the epidermis secretes; a pigment for the skin.
The more melanin a person has, the darker his/her skin is.
Part of it is the blood near the surface, the rest is a dye called melanin in certain cells within the skin.

The function of pigment is just like saying what does the heart do? its an easy question... it is just the primary colour of your skin... its the chemicals in your body that make your skin have a color! and that's the scientific answer!
Sunlight (sun's UV radiation) is the major environmental factor that affects skin color in humans. Skin pigmentation (melanin) is responsible for skin color and it evolves primarily to regulate the amount of ultraviolet radiation penetrating the skin.
Skin color is a polygenic trait. A polygenic trait is one that is controlled by multiple genes. Each gene for skin color deposits no pigment, some pigment, or lots of pigment. The additive effect of the deposited pigment from each gene for skin color results in a whole spectrum (continuum) of color. Also, skin color is affected by the environment, which further increases the variation in human skin color.

Psychology does not influence skin color.The physiological factor that determines skin color is the level of melatonin.
The pigment which determines skin color is melanin.

melanin. melanin also determines the color of your eyes. the more melanin, the darker the color.
The skin color of either parent can effect the skin color of the child.
What brown pigment determines skin color
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.

Can not be done. Skin color is the result of several things. DNA determines eye, hair, and skin color as well as other things. Melanin pigment produces skin color and freckles. The less melanin the whiter the skin. You can not change it. Be proud of who you are.
