In an effort to prevent restaurants from refilling empty Heinz bottles with competing ketchup brands, a clever solution emerged. Heinz has added a red border to the bottle’s label that matches the colour of their product. They selected the Pantone colour 7626C as the corresponding red. Now diners can compare the colour of the bottle’s contents to the red on the label to confirm that the ketchup is the real thing. Heinz refers to this feature as the “Label of Truth” and discerning ketchup lovers everywhere are now on red alert.
