A recent study exploring consumer preferences for candy colors has identified red as the most favored choice, attributing this preference to evolutionary and psychological factors. Conducted by researchers in India, the study examined how color influences sweet selection, using Life Savers candies produced by a U.S. brand as the test subject.

The research involved over 100 participants, both men and women, who were asked to rank their favorite candy colors from a variety of options. Results showed that 43 percent of respondents selected red as their preferred color, followed by blue at 26 percent, orange at 15 percent, green at 10 percent, and yellow at just 5 percent. The disproportionate unpopularity of yellow candies, the researchers noted, may stem from their common association with sour flavors, making them less appealing compared to other colors.

The authors of the study, published on the Open Science Framework, suggest that the dominance of red candy preference is linked to a cognitive process known as "perceptual fluency." This process reflects the brain’s ability to quickly and easily associate the color red with concepts of warmth, ripeness, and sweetness, factors that likely originate from evolutionary experience with red-colored fruits and foods signaling edibility and energy-rich nutrition. In contrast, other colors were linked to different emotional or flavor expectations. Blue, for example, was associated with calmness and peace, which may contribute to its moderate popularity, whereas yellow triggered expectations of sourness, contributing to its low ranking.

The researchers emphasized that the emotional responses elicited by different colors can shape consumer behavior and influence product appeal. They concluded that the visual appeal of red candies carries a competitive advantage due to these psychological and evolutionary associations, potentially explaining why red sweets are often chosen first and fought over in social settings.

This study adds to a growing body of research on how sensory perceptions interact with evolutionary biology and consumer preferences, offering insight relevant for product marketing and design within the confectionery industry.
