The Shades of Morality: The Effects of Light Temperatures on Moral Decision-Making

Abstract

This study explores whether the colour temperature of lighting affects moral decision-making, using research on morals and the influence of light on the mind. Two types of lighting were used: yellow-white light and blue-white light. Yellow-white light was hypothesized to elicit emotional responses, while blue-white light was hypothesized to promote logical reasoning. Moral scenarios were presented to participants to measure their responses as they were exposed to the different light variables. In addition to the hypothesis, this study aimed to answer the question of whether or not the colour temperature of lighting influences one’s moral outlook on a decision. While the results were not statistically significant, this experiment could easily lead to revised versions.
