I found that in 1942 a Russian scientist S.V. Krakov wrote an article in the Journal of the Optical Society of America about color and the autonomic nervous system. In 1958 he was able to demonstrate the effect of red vs. blue on the nervous system. He found that red stimulated the sympathetic part while blue stimulated the parasympathetic part of the system. In the same year, the color researcher, Robert Gerard was able to corroborate Krakov's findings by having 25 males sit in front of a screen with red on it for 10 minutes. He found that the red increased their blood pressure, arousal, respiratory movements, and the frequency that they blinked their eyes. He then had them sit in front of a screen with blue or white
