1) Each light stimulus towards eyes influenced the velocity of blood stream in cutaneous microcirculation of the human body.
2) By the same color stimulation, the stronger light influenced their change less, such as the yellow light of 100lux, showing much more change of the cutaneous microcirculation, compared with the same color light of 600lux.
3) By the same lux, different colors' stimuli influenced the microcirculation. The longer of the color wave-length, the stronger were the influences of the microcirculation, so that the largest influencing color was red, next yellow, then green and the weakest was the blue light.
4) By the same color and by same lux, according to the level of the anxiety state, the color light stimuli influenced the microcirculation.
The higher the anxiety level the higher was the circulation in velocity, except the green light stimulation.
