Overview
March 17th is one of the most fun holidays for permanent lights. Shamrock green across the entire roofline is a statement. Add gold accents for a pot-of-gold effect, or go full rainbow for the ultimate St. Paddy's celebration. Green and gold together create one of the warmest, most festive looks of the year.
St. Patrick's Day is one of those holidays that permanent lights were made for. It's a single-day celebration in the middle of March — nobody is going to install temporary green lights for one evening. But with a GOULY system, you tap your phone on March 17th and your entire roofline turns shamrock green. It takes two seconds, it looks incredible, and every neighbour who drives past knows exactly what day it is. Green and gold on a roofline is one of the most striking colour combinations in the entire GOULY library.
The GOULY app includes multiple St. Patrick's Day patterns, from a simple all-green display to creative combinations with gold accents and even a rainbow chase that leads to a static gold section — the rainbow leading to the pot of gold. You can download these patterns for free, customize the shade of green to match your preference, and schedule the display to activate at sunset on March 15th so you're covered for the whole St. Paddy's weekend.
Green and gold also transitions beautifully into spring lighting. After St. Patrick's Day, you can shift to a softer green or warm white for general spring curb appeal, then transition to Easter pastels a few weeks later. Your permanent system gives you a seamless seasonal flow — winter white to Valentine's red to St. Paddy's green to Easter pastels to summer warm white — all from the same installation, all controlled from your phone.

The permanent advantage
St. Patrick's Day falls on a single day in mid-March, and nobody is installing temporary green lights for one evening. Outdoor St. Paddy's lights barely exist at retail, and even if you found them, March weather in Calgary makes ladder work cold, slushy, and miserable. A permanent system makes St. Patrick's Day lighting not just possible but delightful. One tap turns your roofline shamrock green, one tap turns it back to white the next morning. The whole process takes less time than pouring a pint of Guinness.
Scheduling tip
Schedule green and gold for March 15th through 18th. The weekend around St. Paddy's is as important as the day itself.
