Wang and Chang report that their “study takes popcorn packaging as an example to explore the impact of packaging colour on consumers’ taste perception and preference evaluation. . . . Four experimental package design colours (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.”
