The Power of Periwinkle™ is a global, volunteer-led initiative that shines a light on stomach cancer awareness every November. Since 2017, when My Gut Feeling first launched the campaign, landmarks and community spaces around the world have been illuminated in periwinkle blue—the official colour of stomach cancer awareness.

What began with a 6 sites across Canada has grown into an international movement, with more than 150 locations now participating across continents. From iconic city skylines and historical landmarks to local community hubs, each glowing site is a beacon of hope, awareness, and solidarity for everyone impacted by stomach cancer.

This year, on November 30, 2025, cities across the globe will once again come together in light—raising visibility, honouring those affected, and inspiring action in the fight against stomach cancer.

A Call for Photographers!

On November 30, 2025, landmarks around the world will glow in periwinkle blue for The Power of Periwinkle™. We’re looking for volunteer photographers to help capture this magical moment and share the light of stomach cancer awareness in their city or town.

If you live in the city of one of our sites and would like to be part of this inspiring event, please reach out to events@mygutfeeling.ca
