3 Things to Know About Cooler Color and Ice Retention

Light-colored coolers keep ice longer in direct sunlight White or light coolers reflect sunlight, while dark colors absorb it and turn it into heat. A dark cooler heats up faster and melts ice quicker.

Lightness matters more than hue A light blue cooler works better than a dark blue one. The key factor is how light or dark the color is, not whether it’s blue or green.

Shade is still better than any color No color beats keeping the cooler in the shade. But if it must sit in the sun, choose white or a very light color.
