Iridescent (from Latin iris 'rainbow') Displaying a spectrum of luminous colors that shimmer and change due to interference and scattering as the observer's viewing angle changes.
Pearls, beetles, butterflies, cuttlefish and other cephalopods, hummingbirds, bornite, bismuth, soap bubbles, opals, DVDs and oil on wet pavement all exhibit iridescence caused by redirected light. Coloration caused by micro- or nano-structures is referred to as "structural color" and is a common cause of iridescence in the natural world.
I was fascinated by the diverse manifestations of iridescence in nature and by the physics of iridescence, which links color and structure. I was also struck by the poetry of it: it is only by looking at something from different angles that we fully appreciate its beauty and complexity. Iridescence contains textures that shimmer, or that were created with processes that parallel the diverse directions, angles, and fluctuations that produce iridescence.
