Abstract
The hue-heat hypothesis suggests that in environments dominated by red, people tend to feel warm, while in environments dominated by blue, they feel cool. If color can influence our perception of temperature and gaze behavior, our attention to colors may also change as an adaptation to temperature variations. Therefore, this study aimed to clarify the differences in the level of attention to warm and cool colors when presented in a somewhat warm environment (temperature 33°C, relative humidity 50%). We used an oddball task to compare reaction times, event-related potentials, latencies, and omission errors while presenting red and blue images. The results did not reveal any significant differences between the conditions. It is possible that the stimuli used in this study, consisting of only three colors, led to habituation or boredom, diverting attention from the task. Further research may consider increasing the variety of colors or incorporating text to increase the task's difficulty.
