Fresh Label

"Design studio To-Genkyo proposes a new method of tracking a foods expiration date by using a universally recognizable visual. The new design keeps people honest by changing colors based on the level of ammonia the food emits as it ages. After it has passed its expiration date the barcode is no longer readable, making it impossible to sell."
