Chromotherapy, sometimes called color therapy, colorology or cromatherapy, is an alternative medicine method, which is considered pseudoscience. Chromotherapists claim to be able to use light in the form of color to balance "energy" lacking from a person's body, whether it be on physical, emotional, spiritual, or mental levels.
Avicenna (980-1037), seeing color as of vital importance both in diagnosis and in treatment, discussed chromotherapy in The Canon of Medicine. He wrote that "color is an observable symptom of disease" and also developed a chart that related color to the temperature and physical condition of the body. His view was that red moved the blood, blue or white cooled it, and yellow reduced muscular pain and inflammation.
Practitioners of ayurvedic medicine believe the body has seven "chakras," which some claim are 'spiritual centers', and which are held to be located along the spine. New Age thought associates each of the chakras with a single color of the visible light spectrum, along with a function and organ or bodily system. According to this view, the chakras can become imbalanced and result in physical diseases, but application of the appropriate color can allegedly correct such imbalances. The purported colors and their associations are described as:
