Wang and Chang add to the body of literature linking colors and tastes. They report that their “study takes popcorn packaging as an example to explore the impact of packaging color on consumers' taste perception and preference evaluation. . . . Four experimental package design colors (red, blue, yellow, and white) and three popcorn tastes (sweet, salty, and tasteless) were used. . . . The results of this study indicated that . . . yellow and red packaging are suitable for a sweet product, blue is suitable for a salty product, and white is suitable for a tasteless product.”
