Abstract
This study examines the impact of photograph background colors on the impression of individuals. An evaluative experiment was conducted using plain white and light pink and sky blue backgrounds, which are commonly utilized in identification photos. The findings suggest that the change in impression induced by background color varies according to the gender of the evaluator. Notably, a pink background enhanced the impression of femininity and attractiveness in women as judged by male evaluators. Conversely, it diminished these impressions when evaluated by females. This outcome partially replicates existing research that indicates a red background increases the attractiveness of women as perceived by male evaluators. It also suggests the involvement of new factors, such as a backlash against gender role stereotypes, in influencing these impressions.
