(Background and Purpose) In modern living spaces, many color environments are being changed by several purposes, and space is created, and color is applied in consideration of a better color environment. In this context, interest in the color of space has rapidly increased, and consideration of a healthy spatial environment is a very natural consequence. Therefore, this paper studies the unexplored area of physiological aspects of pure color and its effect on spatial design, through the observation of response characteristics collected from an EEG experiment. Therefore, this is a very important study that can be used as a basis for future research through EEG experiments, which is a method for assessing emotions or evaluating cognitive responses by the unconscious level of human cognitive activity through brain response to pure color. (Method) This study analyzed and summarized the characteristics of the experiment, with a focus on the stimulus color, as to how the human brainwaves respond to pure color. The experiment was carried out for 32 subjects. In the experiment, pure color presented in the NCS (Natural Color System) was divided into eight stages and stimulated by color codes. (Result) In particular, the objective EEG instrument, certified at national level was, used to derive objective experimental results, and objective test results were derived by combining the experimental results and analyzing them with a significance probability of SPSS 22.0, a statistical verification step. Especially, in the experimental environment and conditions, EEG response of the physiological aspects to the pure color response was summarized by reducing experimental errors affecting the environment of experimental space, selecting objective subjects, and using the experimental method of applying VR for direct color stimulation. (Conclusion) Summarizing the results with the probability of significance of p<0.05 in the indicators of RAB and SEF50 that can determine the distribution of arousal and relaxation in the experimental results, the arousal distribution with high brain activity was high in RAB in Y, R; and the overall arousal distribution was shown in RAB in Y50R. Also in R50B, B, G, and G50Y, there was a lot of the distribution of relaxation in RAB, and the change in increasing brain activity was shown in B50G and G50Y. These results showed that warm colors do not awaken the brain unconditionally, and cold colors do not cause unconditional relaxation. Also, the contents of each color code of pure color were presented. |
