- The “black Irish” are those who have black hair AND blue eyes (most Spanish are not blue-eyed). The “black Irish” also have very distinct facial features. They have sharp Celtic facial features rather than what you would see in say the Germanic and other Indo-Europeans.
- The “brown Irish” are brown-eyed and brown hair (or even black hair – hair not the factor except it be dark).
- The hair by itself is significant only in the “red Irish” which is only the read-haired and any color eyes, usually light eyes (all from the constant Nordic invasions).
- Other hair variations come form Nordic and / or other invaders.
I know some folks have a problem with two ideas: (1) very scholarly research shows the origin of the Celtic people before their migrations was in (now called) Bosnia and they were ferocious fighters against the Romans before loosing badly and pushed out and (2) forgeting about religion, one cannot discount the stories of the Irish being a part of the lost tribes of Israel (match the very distinct look of some the black haired and blue-eyed Ashkonozi Jews mostly scattered to German and Russian geographical areas and you see a very striking similarity).
