Label paper for food freshness

Only fresh enough ingredients can make the top delicacy, a well-planned candlelight dinner, with good wine, good food and beauties. But it is frustrating that all of them are ruined by not fresh ingredients. Fortunately, the label that can mark the freshness of ingredients has appeared. It not only saves your stomach but also rescues your romantic heart.

Like an hourglass, the more blue on the top means the fresher, and with the time going, the blue leaks to the bottom slowly. The more blue on the bottom means the less fresh.
