Turks were originally Mongoloid. Look at the people of Central Asia today who were the original Turks. Turkish leaders led small groups of Turkish men into what is now Turkey. They bred with the Byzantine women there. There were red haired blue eyed people in Turkey mostly in Galatia which was settled by celts in the 3rd Century BC. (galatia is the same as Gaul, Gael, Galway, Galicia btw)
