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. Research has shown it is ineffective.
Color therapy is distinct from other types of light therapy, such as neonatal jaundice treatment and blood irradiation therapy which is a scientifically accepted medical treatment for a number of conditions, and from photobiology, the scientific study of the effects of light on living organisms.
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.
American Civil War General Augustus Pleasonton (1801–1894) conducted his own experiments and in 1876 published his book The Influence Of The Blue Ray Of The Sunlight And Of The Blue Color Of The Sky about how the color blue can improve the growth of crops and livestock and can help heal diseases in humans. This led to modern chromotherapy, influencing scientist Dr. Seth Pancoast (1823-&nsash;1889) and Edwin Dwight Babbitt (1828-–1905) to conduct experiments and to publish, respectively, Blue and Red Light; or, Light and Its Rays as Medicine (1877) and The Principles of Light and Color.
In 1933, Indian-born American-citizen scientist Dinshah P. Ghadiali (1873–1966), published The Spectro Chromemetry Encyclopaedia, a work on color therapy. Ghadiali claimed to have discovered why and how the different colored rays have various therapeutic effects on organisms. He believed that colors represent chemical potencies in higher octaves of vibration, and for each organism and system of the body there is a particular color that stimulates and another that inhibits the work of that organ or system. Ghadiali also thought that by knowing the action of the different colors upon the different organs and systems of the body, one can apply the correct color that will tend to balance the action of any organ or system that has become abnormal in its functioning or condition. Dinshah P. Ghadiali's son Darius Dinshah continues to provide information about color therapy via his Dinshah Health Society, a nonprofit organization dedicated to advancing non-pharmaceutical home color therapy, and his book Let There Be Light.
Science writer Martin Gardner had described Ghadiali as "perhaps the greatest quack of them all." In 1925, Ghadiali was accused of rape and arrested in Seattle and sentenced under the Mann Act for five years at the United States Penitentiary, Atlanta. According to Gardner, photographs of Ghadiali at work in his laboratory are "indistinguishable from stills of a grade D movie about a mad scientist."
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:
|Color||Chakra||Chakra location||Alleged function|
|Red||First||Base of the spine||Grounding and Survival|
|Orange||Second||Lower abdomen, genitals||Emotions, sexuality|
|Yellow||Third||Solar plexus||Power, ego|
|Green||Fourth||Heart||Love, sense of responsibility|
|Blue||Fifth||Throat||Physical and spiritual communication|
|Indigo||Sixth||Just above the center of the brow, middle of forehead||Forgiveness, compassion, understanding|
|Violet||Seventh||Crown of the head||Connection with universal energies, transmission of ideas and information|
According to a book published by the American Cancer Society, "available scientific evidence does not support claims that alternative uses of light or color therapy are effective in treating cancer or other illnesses".
Photobiology, the term for the contemporary scientific study of the effects of light on humans, has replaced the term chromotherapy in an effort to separate it from its roots in Victorian mysticism and to strip it of its associations with symbolism and magic. Light therapy is a specific treatment approach using high intensity light to treat specific sleep, skin and mood disorders.
