Sound and color therapy uses specific colors and sound frequencies to promote healing on emotional, mental, and physical levels. Color therapy involves exposing patients to colored lights, while sound color therapy plays the corresponding sound frequencies of the rainbow colors, measured in hertz. Both aim to relax or stimulate cells in targeted ways. Each color has a precise frequency between 470-700Hz that is said to produce the desired healing effect when scientifically applied. Similarly, emotions and thoughts are believed to have signature frequencies that can materialize corresponding experiences when the right sound is used.
