As an expert in cultural and ethnic studies, I can provide you with an understanding of the term "Black Irish." The term "Black Irish" has been used to describe people with dark features, particularly dark hair and blue or dark eyes, who are of Irish descent. It is a colloquial expression rather than a scientific or anthropological term. The "Black Irish" are often thought to have inherited their distinctive features from the Spanish, specifically from the survivors of the Armada shipwrecks off the Irish coast in the late 16th century, or from earlier contact with the Phoenicians or Celts.

However, it's important to note that the term has been a subject of debate and there is no consensus on its origin. Some argue that the term is a racialized term used to describe Irish people with darker features, while others see it as a way to acknowledge the diverse genetic heritage within the Irish population.
