A '''spectral color''' is a [[color]] that is evoked by [[monochromatic radiation|monochromatic light]], i.e. either a [[spectral line]] with a single [[wavelength]] or [[frequency]] of [[light]] in the [[visible spectrum]], or a relatively narrow [[spectral band]] (e.g. [[laser]]s). Every wave of visible light is perceived as a spectral color; when viewed as a [[continuous spectrum]], these colors are seen as the familiar [[rainbow]].
'''Non-spectral colors''' (or '''extra-spectral colors''') are evoked by a combination of spectral colors.
