Abstract
A light control material is provided for displaying color images having microstructures either on its surface or within the material which reflect a selected color and bandwidth of light in accordance with their physical characteristics. In an exemplary embodiment, the microstructures are stepped structures which reflect a particular color and bandwidth of light in accordance with the height of the steps of the stepped structures. In alternative embodiment, the microstructures are ribbed structures or crystal like structures designed to reflect a selected color and bandwidth of light. In addition, methods of fabricating the material are provided.
