Impact of Environmental Colors on Human Aggressiveness: Insights from a Minecraft-Based Behavioral Study

This study explores the influence of environmental colors on human behavior, specifically focusing on aggressiveness and passiveness. Color is widely regarded as an influential environmental factor shaping human behavior, yet existing studies present conflicting evidence regarding its impact on aggressiveness and passiveness. This study employed Minecraft as a controlled digital platform to investigate whether exposure to different colors influences both the frequency and nature of participant interactions (aggressive versus non-aggressive), and whether prolonged exposure amplifies these effects. Anonymous online participants were exposed to various colors before interacting with non-player characters simulating human-like encounters. Three key outcomes were measured: (1) total interactions per color, (2) ratios of aggressive to non-aggressive interactions per color, and (3) the effect of varying exposure durations on aggressiveness. While no significant overall differences in interaction frequency were observed among the colors, post-hoc analyses revealed that Red and Black elicited significantly more interactions compared to Green. Additionally, Red, Yellow, and Black were associated with higher ratios of aggressive behavior relative to Green or White. Prolonged exposure to Red also appeared to intensify aggressive responses. These findings underscore the potential role of environmental color in shaping online social behaviors and highlight the importance of environmental settings in areas ranging from online communication platforms to digital marketing strategies.
