Delicious-Looking Package Color of Bottled Black Tea
Three kinds of bottled black tea were prepared, and each black tea was poured into a plastic bottled wrapped with eleven kinds of colored labels. In this study, participants observed the black tea in the plastic bottle with one of the colored labels, and evaluated “predicted sweetness”, “predicted sourness”, “predicted bitterness”, “predicted roasted-flavor” and “predicted deliciousness”. Subsequently, they evaluated the impression using the semantic differential method with seventeen pairs of adjective. According to the results, the red label could make the bottled black tea visually sweet, and the black label could make it visually bitter. Also, the yellow and yellow-green labels made the black tea more familiar and healthy, and the blue-green and blue labels made it more refreshing and sophisticated, Consequently, the package color of the plastic bottle can control the deliciousness of the black tea, and can determine the impression of the bottled black tea.
