How the Color of St. Patrick’s Day Went From Blue to Green

St. Patrick’s Day usually conjures images of partying, Catholicism, Irish nationalism and, perhaps most famously, the color green: green clothes, green shamrocks, green beer and green rivers.

So my students are often surprised when I tell them that St. Patrick’s Day was once a solemn feast day when you’d be far more likely to see the color blue. In fact, there’s even a color known as St. Patrick’s blue.

‘True blue’

Historians don’t know much about St. Patrick. But they believe he was born in the fifth century as Maewyn Succat.

He wasn’t Irish; rather he was born in Wales, the son of a Roman-British official. He was, however, captured by Irish pirates and enslaved in Ireland. After six years he went back to Britain but returned to Ireland as one of the missionaries to convert Irish pagans to Christianity. At some point he adopted the Latin name Patricius. In the 10th century, the first evidence of St. Patrick being a beloved figure in Ireland emerged.

In the early 17th century, Luke Wadding, an Irish priest, persuaded the Catholic Church to make March 17 a feast day for St. Patrick.
