This is found in its greatest distribution in Asia, pre-Columbian Americas and Africa. Black hair is also particularly common in people of Asia, Eastern Europe, Latin America, Southern Europe and Africa regardless of ethnolinguistic affiliation. For example, Southern Europeans are particularly noted for their straight or wavy black hair, and it can be combined with either dark (such as brown) or light (such as green, gray or blue) colored eyes. Irish people with these traits are sometimes known as the "Black Irish". Though this characteristic can be seen in people throughout the United Kingdom and Northwestern Europe, it becomes more common in Eastern Europe.
