The popularization of LED and the development of the control technology of the lights provide chromatic lights such as a red, blue, green. The chromatic lights are expected from the psychology and the physiological effect of color. And it is predicted that chromatic lights are innovated positively into a life space. This research is about the image of chromatic lights is examined using heart rate variability and psychological methodology, i.e., paired comparison test. The subjects of paired comparison test were 14 healthy participants (age 21.9±3.7 years old). The subjects of heart rate variability were 7 healthy participants (age 24.0±3.9 years old). We examined from the two viewpoints. 1. In the results of paired comparison test, the score of the white-ice, yellow and green demonstrated greater scores compared with the other. The score of blue, red and pink decreased to lower values compared with the other. 2. In the results of heart rate variability, the mean values of HF of white-Ice, yellow and green demonstrated greater values compared with the other. The mean values of HF of blue, red and pink decreased to lower values compared with the other. It is thus concluded that, using physiological parameters and questionnaire, it is possible to analyze the effect of chromatic lights on living organisms.
