what was the original color of st patrick's day

The original color associated with St. Patrick and early St. Patrick’s Day was blue , not green.

Quick Scoop: Short Answer

  • Historians say St. Patrick’s original color was a light or sky blue , often called “St. Patrick’s Blue.”
  • Early depictions and heraldry linked to him and to the Kingdom of Ireland used this blue long before green took over.

How Did It Start as Blue?

In medieval and early modern art, St. Patrick is often shown wearing blue robes rather than green. This visual tradition helped establish blue as his first symbolic color.

Later, in 1783, the British crown created the Order of St. Patrick, a chivalric order for Ireland whose official color was a pale sky blue known as “St. Patrick’s Blue.” That shade appeared on sashes, mantles, and symbols connected to the order and reinforced blue as Ireland’s formal color at the time.

In other words, if you walked into an 18th‑century St. Patrick’s Day ceremony, you’d have seen far more blue than green.

How Did It Change to Green?

Over time, several cultural and political shifts turned St. Patrick’s Day green:

  1. Shamrock symbolism
    • Tradition holds that St. Patrick used a three‑leaf shamrock to explain the Holy Trinity, and the plant’s natural color tied the faith story to green.
 * “Wearing the green” as a shamrock pin or sprig became a devotional and cultural habit.
  1. Irish nationalism and rebellion
    • During the late 18th‑century Irish nationalist movements, especially around the 1798 rebellion, green and the shamrock became symbols of resistance and Irish identity.
 * Nationalist uniforms, flags, and songs emphasized green, pushing blue into the background.
  1. “Emerald Isle” and global imagery
    • Ireland’s lush landscape fed the “Emerald Isle” nickname, strengthening the link between the country and the color green.
 * As Irish communities migrated, especially to the United States, parades, decorations, and marketing leaned heavily into green—clothes, beer, lights, even rivers.

Little Story to Remember It

Imagine walking into an 18th‑century Dublin celebration on March 17: instead of seas of green T‑shirts, you’d see formal coats and sashes in a dignified blue , tied to church, monarchy, and order. Fast‑forward to today and that scene has flipped—shamrocks, “Emerald Isle” imagery, and Irish nationalism have washed the day in green, leaving blue as a quirky bit of trivia most people only rediscover around St. Patrick’s Day.

TL;DR: The original color of St. Patrick’s Day—and of St. Patrick himself—was a light “St. Patrick’s Blue,” but over the 18th and 19th centuries, green took over through shamrocks, nationalism, and the “Emerald Isle” image.
