Color wheel (optics)

Color wheel (optics)
An 1895 mechanical color wheel, used for experiments with color vision.

A color wheel or other switch for changing a projected hue (e.g., for an optical display) is a device that uses different optics filters within a light beam. Common usage includes continuously-rotating wheels for seasonal home displays (e.g., at Christmas) and controllable color wheels for a particular instrument (e.g., SeaChanger Color Engine for stage lighting), while non-wheel devices include scrollers and semaphore types with lever arms (e.g., on the 1897-1917 Grand Army Plaza fountain).
