Abstract
A light control material for displaying a color image. The light control material includes a material body including a plurality of microstructures. The microstructures are designed to produce an additive color perception of one or more colors and designed to reveal an image when the intensity of light reflected from a selected number of the microstructures is modulated. The selected microstructures can be modulated by one or more of modifying, obliterating, obscuring or covering up the selected microstructures. In one embodiment, the microstructures, prior to modulation of the selected number of microstructures, produce a uniform white additive color perception.
