Pigment, lipochrome, eumelanin and eye colour

What is pigment?

Brown eye colour
Pigment is something we all find in the human eyes. The type and amount of pigmentation in the iris determines the colour. There are two types of pigment cells. The first type is called eumelanin and the second one is called pheomelanin (or lipochrome). When you have a lot of eumelanin pigment cells, chances are high you have brown eyes. When your stroma (iris) contains only a small amount of the eumelanin cells, chances are high you will have blue eyes.
