Effects on impression by water surface reflection were verified by experiments with participants. As results, light color was more preferred than daylight color. Calmness increased when the luminance value was lower than about 8000 cd/m2. The higher the luminance value, the higher the evaluation of sharpness and glitter. When the water surface had small and medium waves, the evaluation value of calmness, glitter and beauty was higher than when there was no wave. Calmness and beauty were rated higher for small waves than for medium waves. Based on the above findings, lighting schemes with water reflections should be implemented.
