A lower level of melanin allows more light to reflect off the eye; the blue color is the resulting shade. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. Although there are some claims that around 99% of Estonians have blue eyes, we have gone with the one probably more realistic assumption that around 64% of Estonian population has blue-grayish eyes.
