The symbolism of color is unquestioned. Evidence of this can be seen in any sales advertisement and every sports team choice of uniform colors. Color has a direct connection to the human mind; it is the reason why seeing red makes someone think about passion and seeing green makes them think about the calming aspects of nature. The effect of color goes beyond these simple associations, on a subconscious level; color can have direct effect on an individual's mood. This basic theory, along with more in depth theories about the effect of color on the seven chakras and bodily function, led to the formation of many alternative forms of medicine. In a more literal sense, it is theorized that the importance of color lies in the body's need to be exposed to sunlight. People in present day, do not receive nearly as much exposure to sunlight as humans a generation ago, let alone a few centuries ago. The fact that individual color frequencies all make up white light, may lead to specific light deficiencies being treated with certain colors. Color therapy is one form of alternative medicine that relies heavily on concentrated exposure of different types of lights, intended to promote healing and psychological and physical level.
A major tool used by those who practice color therapy is the color lights. Color lights are usually created with the use of a lamp and either color shade filters or colored crystals. Once it is established by a color therapy expert which type of color is needed for a specific ailment, treatment with colored lights can then begin. A color light treatment can be a general bath of light to the whole body for a few minutes at a time. It can also be a more concentrated ray of light, focused on a particular area of the body that needs attention. An individual with an upset stomach for example, can be treated with a blue colored light focused on their stomach for 10-15 minutes. Colored lights can also be strategically placed along different parts of the body in conjuncture with the seven chakras or commonly used acupuncture points on the skin. In addition to increasing overall health and mental state, the use of colored light therapy has been used to treat common problems such as insomnia and jet lag. It has also been used to treat more serious disorders, such as depression.
Colored lights play a major role in alternative forms of medicine such as color therapy. They have even gained more mainstream medical success, with the positive effects of treatments gaining more notoriety.
