Color elicits a total response from human beings because the energy produced by the light that
carries color effects our body functions and influences our mind and emotion. In 1976, Rikard
Kuller demonstrated how color and visual patterning affects not only the cortex but also the entire
central nervous system1
. Color has been shown to alter the level of alpha brain wave activity, which
is used in the medical field to measure human alertness. In addition, it has been found that when
color is transmitted through the human eye, the brain releases the hormone, hypothalamus, which
affects our moods, mental clarity and energy level.
