an individual.
Melanin-producing cells are called Melanocytes which are
located in the bottom layer of the skin's epidermis, the middle layer of the
eye, heart, etc.
A mere explore to sun leads to the production of melanin by
our skin cells. Melanin production is increased along with you are more exposed
to the sunlight.

1. Eumelanin; responsible for the brown colour of our skin
and dark colour to hairs.

reddish shade.
3. Neuromelanin; is a dark pigment found in the brain and
loss of this melanin may cause several neurological disorders.
