Analysis of the impact of different background colors in VR environments on risk preferences

Metaverse virtual reality (VR) technology offers an environment that provides a sense of presence that cannot be achieved through traditional online interactions. Although this technology is used in education and industry, challenges remain to be overcome for further penetration into society. In this study, we conducted an experiment using a risk preference task in blue and red spaces to verify color impressions and their effects in VR environments. Consistent with previous studies, high calmness was observed in the blue space. However, contrary to expectations, the risk preference task results showed risk-averse behavior in red space but not in blue space. Therefore, conventional color psychology may not be applicable to constructing the same space in a virtual environment. Previous studies have shown consistent experimental results regarding emotional responses to color stimuli; however, no consistent outcomes have been reported regarding cognitive performance. This is because the effect of color impressions is thought to depend not only on the color itself but also on what is recalled. The results of this study suggest that red in a VR environment may be interpreted as a warning color, preventing people from losing focus.
