Each one of the 7 chakra energy centers of the body has a direct correspondence to a particular color of the rainbow spectrum. Each color has a distinct frequency or vibration depending on its wavelength. Each chakra has a direct energetic connection to the vibrational frequency of each color.
Working with the colors is an effective way to heal and energize the chakra that the color is associated with. Each color also has unique qualities that can affect your mood and energy and can be used in meditation and visualization for different healing purposes. The premise of working with chakra stones or crystals is that each stone has the purpose of magnifying or balancing the energy center you’re focusing on.
