iridescence(redirected from Chromatic shift)
Also found in: Dictionary, Thesaurus, Medical.
iridescence (ĭrˌədĕsˈəns), exhibition of rainbowlike colors on a surface. It usually results from interference when light composed of different wavelengths is reflected from the superficial layers of organic or inorganic substances, e.g., minerals, mother-of-pearl, and the feathers of birds. Iridescence greatly enhances the value of certain gems.
