Eye-catching for shoppers: Colorful Nutri-Score labels more effective than gray

Anyone seeking to purchase healthy products at the supermarket needs clear guidance. Nutritional labeling schemes, such as Nutri-Score labels, are designed to help with that. The Nutri-Score front-of-pack label shows a five-color system from favorable nutritional composition in green (A) through to unfavorable in red (E). The scheme is optional on products across the EU but has been adopted by companies in several countries, for instance, Germany and the Netherlands. Some supermarkets also print a gray version on the price tag, but the colorful version on the shelf also attracts more attention here.
