(involving all colors, i.e., all wavelengths)

The word Panchromatic, which basically means "all colors" is occasionally used in astronomy to indicate a very wide span of Wavelengths. The word might, for example, be used for a Spectrographic Survey that covers a very wide range of the spectrum, a range in which Visible Light is just a small part.
