In this study we investigated an interaction effect between lighting color and food color in order to stimulate or discourage one"s appetite. We facilitated the LED as an additional chromatic lighting source, and observers selected the best and worst lighting colors by themselves using a "Mini Living Colors" in preliminary test (N = 30) and color picker software in a main experiment (N = 30). Food stimuli were composed of two aspects, type-natural and processed-and complexity-low and high-, and consequently they were grouped into four categories. We measured the selected lighting color in terms of chromaticity (x, y coordination in CIE Chromaticity Diagram) and illumination level (lx), and analyzed the best and worst combinations based on these measurements. White was dominantly preferred as appetitive lighting color, indicating that low purity should be appropriate for food. Moreover, it raises a necessity of a further investigation about the nuances of white lightings. In addition, across the two empirical studies, we found three tendencies: First, except for the white, yellow lighting stimulates while red and blue discourages one"s appetite; Second, when color categories of lighting and food are similar to each other, it stimulates the appetite whereas complementary, it discourages it; Third, the type of food does not act as an influencing factor.
