Shamrocks, Cabbage and Guinness: St. Patrick's Day by the Numbers


As you rummage through your closet to find green clothes to wear on St. Patrick’s Day, you might also want to add a touch of blue to your outfit – the color originally associated with the holiday.

That what Éire’s official color was when it became a Kingdom in 1542. Blue made its debut on the country’s coat of arms, in which a golden harp is depicted on a blue background. St. Patrick, the person the holiday is named for, is associated with the color blue because in several pieces of artwork he is depicted wearing blue clothing.

The color green only became associated with Ireland in the 19th century when it was used during the wave of Irish nationalism to show a separation from the red and blues that were associated with England, Scotland and Wales. It was also used in the new flag of the Confederation of Ireland.

Although there isn’t currently an official national color of Ireland, the most common color associated with the country is now green. Many people who celebrate St. Patrick’s Day assume green is worn because of the greenness of the country’s landscape.
