With the rapid progress of information technology, short video advertising has flourished, and the performance of advertising images can stimulate consumers’ purchase behavior through short video platforms. Drawing on stimulus-organization-response (S-O-R) theory, this study explored the moderating role of short video platforms on the relationship between light and color of advertising photography and brand image and the mediating role of brand image between light and color and consumers’ purchase intention. The data were collected using a questionnaire focusing on consumers who purchased detergent products in major supermarkets in East China. The survey covered 200 respondents from different industries, genders, and education levels in various provinces and cities in East China. Collected data were analyzed using regression analysis. It was found that the light and color of advertising photography have a facilitating effect on consumers’ purchase intention. Furthermore, brand image mediates the relationship between light and color and consumers’ purchase intention. Finally, short video platforms can moderate the relationship between light and color and brand image. This study will encourage scholars to use the S-O-R model in academic research to investigate how advertising affects consumers’ purchase intention and guide companies to use short video platforms to advertise and increase product sales.
