Coors Light fans know that when the mountains turn blue, the beer’s ready to drink. 

We brought the color-changing technology on Coors Light’s packaging to the hands of its drinkers with Chill Polish, a nail polish specially engineered to turn from slate gray to Coors Light blue at specific temperatures. Now even when drinking from a pint, you know when the mountains turn blue.
