We use the medical care room of a nursing home for the elderly as laboratory. We use Semantic Differential method for psychological evaluation, and get two factors. Factor one is to be comfort etc., factor two is to be bright etc. We measure a heartrate and analyze heartrate change, and also measure a secretion quantity of salivary amylase for physiological measurement. Result of heartrate measurement, degree of relaxation of Japanese traditional colors are higher than another colors.

In this experiment there are no intentional relations among degree of relaxation which are measured by SD method and physiological measurement.
