The color of the packaging is an important but tricky element, finds a new study. Foods packed in light-colored packaging may appear healthier.
The aesthetics of food packaging is geared to the assumptions people make about the product within. In "Light and Pale Colors in Food Packaging: When Does This Package Cue Signal Superior Healthiness or Inferior Taste?" Marketing Professors Robert Mai, Claudia Symmank, and Berenike Seeberg-Elverfeldt of Kiel University (Claudia Symmank is also research associate at the Technical University of Dresden) tested consumers' reactions to find out if they associated pale packaging with healthy choices or poor taste and found that it wasn't an either/or situation.
For example, in one of six studies, the authors packaged the same herbed cream cheese in two different colors: light green and regular green. A group of 179 participants was shown the package but not given an opportunity to taste the contents. In a second round, they could also taste it. Study participants who were not particularly health-conscious viewed the light packaging as containing a product that might be healthy, but they assumed from the light-colored package it was also less tasty.
The authors explain, "Unlike taste, healthiness is a credence quality. Since human abilities are too limited to distinguish more or less healthy products by taste...healthiness evaluations were guided by package color even after the consumers had tried the product."
Other studies teased out that color as a tool has the potential to backfire, because, apart from health inferences, light tones tend to signify a lack of tastiness. Detrimental taste inferences are primarily triggered when consumers are unable to taste, making extrinsic cues such as package color particularly important, the authors point out: "Thus, when selling healthy foods to less health-aware shoppers, pale packages can have a deterrent effect. Employing darker tones could be one way to compensate for a perceived taste decrease."
