Abstract: A static color multiview display and method provide a static color multiview image using color-selective diffractive gratings configured to emit directional light beams that encode color view pixels of the static color multiview image. The static color multiview display includes a light guide configured to guide plurality of guided light beams having different radial directions and a light source configured to provide polychromatic light to be guided as the guided light beam plurality. The static color multiview display further includes a plurality of diffraction gratings configured to a scatter out a plurality of directional light beams that encode the color view pixels, each diffraction grating being configured to scatter out from one of the guided light beams a directional light beam having a predetermined color, intensity, and direction corresponding to a color, intensity, and view direction of a color view pixel of the static color multiview image.
