The practice of combining reflexology with color therapy has been used to boost reflexology's effectiveness. The author explains how the different vibrations of each color in the electromagnetic spectrum corresponds to the various frequencies and vibrations of each part of the human body. Just as reflexology uses pressure techniques on the hands and feet which correspond to parts of the body, color therapy can also be applied to these areas to restore health and harmony. Combining color therapy and reflexology is often particularly effective in cases of chronic illness, especially in circumstances where ordinary reflexology may be too harsh.
