      The colour of a person’s eyes depends on the amount of melanin in the cells that make up their eyes. Melanin is the chemical that determines how dark our hair, skin and eyes are. People with lighter eyes (such as blue or green) have less melanin in their eye cells which also means that the amount of lighting around them, the colours of their clothes etc can affect the way in which their eye colour looks. This is not a real change in the colour of your eyes themselves but a change in the way in which people and yourself see them under different conditions.
