The influence of color on the human mood has been documented for centuries, but it may truly be coming into its own in the frenetic world of today. The electromagnetic energy found in light is body-compatible and is easily absorbed by the tissues. Visible incoherent polarized (VIP) light rays range from 480–3,400 nanometers (nm) and possess every color of the spectrum while avoiding ultraviolet (UV) rays. As wavelengths decrease, radiation increases, culminating in cosmic radiation, the highest energy of all.
Sunlight is natural, full-spectrum light. If you shine full-spectrum light on a prism, it splits into the colors of the rainbow, each possessing a different wavelength.
