Why We Wear Green On St. Patrick’s Day

These days green is the Irish color as well as the St. Patrick’s Day color. That wasn’t always so. It used to be blue which would have made it easier for everyone with a Michigan sweatshirt:

Originally the colour associated with Saint Patrick was blue. However, over the years the colour green and its association with Saint Patrick’s day grew.[2] Green ribbons and shamrocks were worn in celebration of St Patrick’s Day as early as the 17th century.[3] He is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pre-Christian Irish, and the wearing and display of shamrocks and shamrock-inspired designs have become a ubiquitous feature of the day.[4][5] Then in the 1798 rebellion in hopes of making a political statement Irish soldiers wore full green uniforms on 17 March in hopes of catching attention with their unusual fashion gimmick.[2] The phrase “the wearing of the green”, meaning to wear a shamrock on one’s clothing, derives from the song of the same name.
