초록

This study aims to evaluate color affect according to color scheme and illuminance change by analyzing color preference and prefrontal EEG alpha and beta signal. First, we measured psychological evaluation by using preference with Likert 7 scale and the subjects' physiological responses by EEG to see the changes of valence (frontal alpha asymmetry) and arousal (the ratio of beta to alpha) to color conditions and illuminant differences. The eight colored spaces were built using computer graphic programs. Two colors, Red and Purple Blue were selected for this experiment, and two types of illuminances(200lx and 500lx). 39 subjects in their 40s and 60s, with normal color vision for their age, participated in a room with the natural light blocked. The results were as follows. (1) When comparing emotional preference, there were also no significant differences by age, but the characteristics of Illuminance have a great influence on psychological response. (2) When comparing EEG signal analysis, there were significant differences by age. Absolute power of EEG signal in their 40s was higher than 60s. (3) When comparing color affect, arousal level in their 40s was relatively higher than 60s, and they showed the happiest emotional state in PB-B with 500lx. In their 60s, valence was found to have a greater influence on the emotional state, and they felt pleasant with complementary color schemes.
