Chromotherapy, sometimes called color therapy or colorology, is an alternative medicine method. It is claimed that a therapist trained in chromotherapy can use color and light to balance energy wherever our bodies are lacking, be it physical, emotional, spiritual, or mental.

Chromotherapists claim a scientific basis for their practice, proposing that colors bring about emotional reactions in people. A standard method of diagnosis is the use of "Luscher’s color test", developed by Max Luscher (*1923) in the early 1900s. When performing chromotherapy, color and light is applied to specific areas and acupoints on the body. Because colors get associated with both positive and negative effects in color therapy, specific colors and accurate amounts of color are deemed to be critical in healing. Some of the tools used for applying colors are gemstones, candles, wands, prisms, colored fabrics, bath treatments, and colored glasses or lenses. Therapeutic color can be administered in a number of ways, but is often combined with hydrotherapy and aromatherapy in an attempt to heighten the therapeutic effect.
