In the brief, almost unconscious moment a shopper reaches for a product, color may carry more moral weight than any written warning. Researchers at Göttingen University have found that the Nutri-Score nutrition label — a five-tier system rating food from green to red — guides purchasing decisions far more effectively when rendered in full color than in grayscale, suggesting that the design of information is inseparable from its power to change behavior. Yet the study also surfaces a quieter paradox: the red warning, the signal meant to protect, failed to deter — revealing that human choice is

Consumers benefit from improved visual guidance on nutritional quality, potentially leading to healthier food choices and reduced consumption of low-nutrition products. However, manufacturers of lower-rated products may face reduced sales, increasing costs for reformulation or marketing adjustments.
Findings support mandatory adoption of color-coded Nutri-Score labeling across EU markets. Policymakers may accelerate standardization requirements, potentially increasing compliance costs for food manufacturers but improving public health outcomes. The ineffectiveness of red 'E' warnings suggests need for alternative deterrent mechanisms.
