The next time you're at a fast food restaurant look around at the decor. The colors are bright, cheery and fun. Not that they don't want you happy, but bright colors such as red, orange and yellow have been proven to stimulate the nervous system and increase your appetite.
Color therapy is based on the fact that physiologic functions respond to specific colors.
Attached to the brain are pineal glands, which control the daily rhythms of life. Different colors give off different wavelength frequencies and these different frequencies have different effects on physical and psychological functions. The example given above with yellow, red and orange in the fast food restaurant is just one way this principle works. Before looking further into more examples of how color therapy has been put into practice, let's look at specific colors and their proven effects. Using colored light for therapy has been in practice a very long time and we see it happening every day, whether we realize it or not.
