Do the Mountains Turn Blue on Coors Light?: 1 Minute to Discover This Iconic Beer's Feature

Yes, Coors Light cans and bottles famously feature a “mountain turns blue” indicator as part of their branding and packaging. When the beer reaches an optimal cold temperature—usually around 46°F (8°C) or colder—the depiction of the Rocky Mountains on the label changes from gray to blue. This provides a visual cue to consumers that their drink is cold and ready to enjoy. It’s an innovative printing technology using thermochromic ink, specifically designed for Coors Light in order to enhance the drinking experience by connecting the product with refreshment cues.
