The structure of an iridescent surface causes a beam of incident light to be split into several beams of light of different wavelengths and so colours. Any change in the nature of the incident light also changes the colours. This effect occurs frequently in nature, for example in fish scales, the wing cases of beetles and peacock feathers. The greatest effect is produced by movement, so that iridescent paintwork shows to its best advantage on moving objects (Alfa Romeo started this) or in locations where the observer is moving (facades and advertisements). As in nature, the effect is mainly used to confuse, to surprise or to add extra dynamism to a surface. A well-known example is the shiny patch on credit cards. An image printed as a prismatic surface using microscopically thin coloured lines changes according to the angle from which it is viewed. Bernd van der Stouw's LENZ iridescent acrylic sheets can be printed with figures that change as the observer moves; the sheets can be applied to elevations and interiors.
