Chromotherapy also known as color therapy, “Color therapy is classified as a vibrational healing modality. Vibrational medicine incorporates the use of chi energies within living organisms such as plants, gemstones and crystals, water, sunlight, and sound.” http://healing.about.com
Healers trained in chromotherapy claim that they can heal a persons energy by using colors. This then balances a persons energy- their physical, emotional or spiritual energy. Each color relates to a separate part of the body. Your chakras need to be aligned in order to heal your body, the lights healers use different colors in order to heal each part of your chakras to help your energy.
Color therapy dates back too many years ago, from India, China, and Egypt. There is different wavelengths in each color, healers use different colored lights to heal each body part, with the color associated with that part.
