This study investigated the relationship between contextualised colours and psychological responses using a semantic differential method. Fruit juice cartons were used as model product packs to elicit psychological responses of several aspects: judgments of the colour harmony of the packages and liking, quality and freshness of the products.

Judgments of these three aspects were influenced by the chromatic and hue differences between the colours of the packages and the colours of fruit pictures on the packages. Second, visual appraisal of freshness was affected by the lightness and chroma of the package colours.
