The development of the light environment in commercial spaces has been gradually increasing with people’s demand for quality of life, and its efficacy is not only limited to meeting the lighting needs of merchandise display, but also meeting people’s psychological comfort and preference needs. Two common attributes of the outer packaging of juice products, namely outer packaging material and color, were used as variables to study their effects on consumer emotional response and the preference analysis of color temperature on the two variables under different color temperature commercial space light environments. The experiment was based on simulating the light environment of convenience stores and supermarkets in indoor commercial space lighting mode. Three color temperatures of 3000, 4500 and 6000 K were selected as the value of the commercial space light environment variables, and the illuminance of 300 lx was used through general lighting. The outer packaging of the juice product adopted three different materials (metal aluminum, composite paper and plastic), and each material corresponded to five outer packaging colors (red, yellow, green, purple, pink). The research results showed that pink and purple were suitable for different materials in different light environments, and were less affected by light environments with changing color temperatures. Among the three materials, composite paper and metal aluminum were more popular with consumers, and less affected by color temperature changes. The light environment of 4500 K color temperature was suitable for different materials, which was the optimal color temperature value in the experiment. Shop owners could optimize the light environment of the commercial space to provide consumers with a more comfortable shopping experience while promoting sales.
