Scientists studying sweet preferences found that red candies are the most favored due to their association with warmth, sweetness, and ripeness. In a study involving more than 100 participants ranking candy colors from US brand Life Savers, 43% chose red as their top choice, followed by blue at 26%. Yellow sweets were least preferred, eight times less popular than red ones because yellow is linked to sour flavors. The researchers attribute this preference to "perceptual fluency," where the brain quickly matches colors like red with expected tastes.

Story summary
Scientists from India published a study on the Open Science Framework revealing that people prefer red Life Savers candies over others. The research involved more than 100 participants who were asked to rank their candy color preferences. 43% chose red as their favorite, followed by blue at 26%, orange at 15%, green at 10%, and yellow at just 5%. Yellow sweets are least favored because the color is associated with a sour taste in contrast to red, which people associate with warmth, sweetness, and ripeness due to perceptual fluency—the ease and speed of brain matching images with expectations.

The researchers, writing in the Open Science Framework, said red likely came top because of a phenomenon known as ‘perceptual fluency’ – the ease and speed with which the brain matches an image with our expectations.
