Gray eyes can also be found among the Algerian Shawia people[52] of the Aurès Mountains in Northwest Africa, in the Middle East/West Asia, Central Asia, and South Asia.

Bicolour Iris Bicolour irises feature up-facing standards that are lightly shaded or medium hued, and down-facing falls that have deeper, contrasting colours. The later additions to the European gene pool, the Early Neolithic farmers from Anatolia and the Yamnaya Copper Age/Bronze Age pastoralists (possibly the Proto-Indo-European population) from the area north of the Black Sea appear to have had much higher incidences of dark eye color alleles, and alleles giving rise to lighter skin, than the original European population. [53] Under magnification, gray eyes exhibit small amounts of yellow and brown color in the iris. [62][63][64][65][66][67][68] This can sometimes produce a multicolored iris, i.e., an eye that is light brown/amber near the pupil and charcoal or dark green on the outer part of the iris (or vice versa) when observed in sunlight.
