    Our eye colour is basically determined by the combination of colour

    pigments on our iris (i.e. the ring of muscle that control the diameter of

    our pupil, which is controlled by reflex involving the mid-brain). In

    essence, there is a pigment called melanin that gives rise to colour in

    the hair, the skin and the iris and the choroids layer of the eyes.

    Melanin is contained within special cells called melanophores, and is

    produced by the metabolism of the amino acid tyrosine. There are a number

    of different type of melanins, and different combination of the different

    melanins give rise to the difference in our eye colours.
