Psychological and Physiological Responses to Color of a Room

摘要

Colors have a direct influence on people's feelings and are intimately connected to their lives.The purpose of this study is to analyze the effect of colors on the living environment to enhance comfortable environment.The fluctuation of heartbeat and brainwaves were measured as an index to estimate the autonomic nerve response and central nerve response evoked by color spaces.The analysis was made using the SD method(Semantic Differential method).An experiment was conducted in a six-mat-apartment(2.35X3.28X2.30m~3),with six different colors applied to the carpets,walls and curtains,to determine the psychological and physiological effects of the colors on people.Results indicate that yellow and off-white raise a brainwave activity and enhance factors of "relaxation and evaluation " working on a parasympathetic nerve response .Warm colors emphasize the factors of "activity" and "the warmth and coolness of color".The HF ingredient and 1/f fluctuation were measured and results indicate that those colors cause a pleasant stimulation in the body of the subject.The effect of cool colors is slight.The study suggests that it is important to balance the factors of "relaxation and evaluation" with those of "activity" and "the warmth and coolness of color" to maximize comfort using in an interior space.
