- Iridescence \Ir`i*des"cence\, n. [See Iridescent.] Exhibition of colors like those of the rainbow, especially a surface reflection which changes color with the angle at which the object is viewed; the quality or state of being iridescent; a prismatic play of color; as, the iridescence of mother-of-pearl. It is due to interference of light waves reflected from the front and back surfaces of a thin layer transpatrent or semitransparent film. [1913 Webster]
