The History and Symbolism of St. Patrick’s Day Colours in Advertising

From parades to product packaging, St. Patrick’s Day colours dominate the marketing scene every March. But have you ever wondered why green is the defining shade of this Irish holiday? More importantly, how do businesses strategically use these colours in advertising and branding to attract customers and boost seasonal sales? This guide dives into the history of St. Patrick’s Day colours, their deeper meanings, and how brands leverage them to create impactful Irish-themed marketing campaigns.

 

The History of St. Patrick’s Day Colours 

Surprisingly, green wasn’t always the signature colour of St. Patrick’s Day. Historically, blue was associated with St. Patrick, as seen in ancient Irish symbols and royal attire. 

How Green Became the Official Colour 

• The Irish Rebellion (1798): During the fight for independence, Irish soldiers wore green uniforms, making it a symbol of national pride.

• The Shamrock Connection: St. Patrick was said to have used the three-leaf clover (shamrock) to explain the Holy Trinity, linking green to Irish heritage and Christianity.

• The “Wearing of the Green”: A phrase originating from Irish folk songs, emphasizing the cultural and political significance of green attire and accessories.

Today, St. Patrick’s Day colours represent more than just a holiday—they symbolize heritage, luck, and celebration, making them a marketing goldmine.
