Ireland is known as the Emerald Isle. Green is traditionally worn on St. Patrick's day to honor the Emerald Isle. Tradition holds that on that day, people who do not wear green are pinched as a reminder to wear green to honor the Emerald Isle.
Today, St. Patrick's Day is the day to wear green, kiss the Blarney Stone (weâll get to that later), and celebrate being Irish (or in some cases, choosing to be Irish for a day). Why do people wear green on St. Patrickâs Day? True or False? Green was not the original color associated with St. Patrickâs Day. The answer is true. Blue was the original color of St. Patrickâs Day and can still be seen on ancient Irish Flags. The color green was later adopted by Ireland in the 19th Century because green is representative of spring, fertility, life, and of course the shamrock.
