Iridescence refers to a play of light and color that can be seen on certain surfaces. It is caused by interference of light waves from different angles and results in a variety of colors depending on the angle of view. Iridescent materials appear to be different colors from different angles, with a shimmering and rainbow-like effect. This effect is often seen on the wings of certain species of butterflies, the shells of certain sea creatures, and on some watches. Iridescent watches have a unique, changing appearance that makes them stand out from the crowd.
