Coffee cup color and evaluation of a beverage's “warmth quality”



Glass color may influence the evaluation of food and beverages as has been reported in a previous study where participants rated a cold beverage presented in a blue glass to be more thirst-quenching than the same beverage poured into a green, yellow, or red glass. Our experiment sought to test whether container color also can affect the perceived temperature of a warm beverage. One hundred and twenty undergraduates were given warm coffee served in cups of different colors (blue, green, yellow, and red) and were asked to indicate which beverage was the warmest. Statistically significant differences among colors were found. The red cup was evaluated as containing the warmest beverage (38.3%), followed by the yellow (28.3%), the green (20.0%), and the blue (13.3%) cups. Conventional associations between warm versus cool colors are used to explain these results. © 2012 Wiley Periodicals, Inc. Col Res Appl, 39, 79–81, 2014
