Package designs stimulate consumers visually and give rise to a sense of aesthetism, thus improving product visibility. In this study, emotions related to color combinations in packaging were addressed, cake packaging designs were tested, and affective design elements regarding styles and colors along with the diverse emotions that resulted were assessed and researched. Four experiments were conducted: Experiment 1 was on the affective characteristics related to types of colored boxes in packaging design; the best type of colored box for cakes was tested. In experiment 2, adjectives for emotions were compiled to identify adjectives for emotional responses to package designs. Experiment 3 was used to examine the fitness of single-color boxes in packaging design; the colors of single-color boxes were examined. In experiment 4, the focus was the fitness of dual-color boxes in packaging design; an experiment on the best color combination was conducted with dual-color boxes, and the results were then collected and analyzed to determine the fittest color combination for cake packaging design. According to the research findings, in the experiment on colored box types used in packaging design, the design with a five-sided trapezoidal design was the most popular, followed by the colored box type with a rectangular handle in the middle; the selection of and experimentation on the adjectives for emotions revealed that Exquisite-Rough was the fittest for the experiment, followed by Lively-Dull; the fittest single-color box was orange (Pantone715 C,L69.6,A37.0,B65.8), followed by gray (Pantone Gray Cool Gray 1C,L86.4,A0.1,B1.1); the fittest dual-color box was in orange and orange red (Pantone Orange 021C, C,L60.0,A65.2,B71.4), followed by orange and black (Pantone Black C,L17.3,A0.8,B3.1). The experiment in this study focused on the color packaging of boxes for cakes; its results provide theoretical and practical references, for future research and orientation, regarding colors and types of colored boxes used for various products.
