Abstract: A system include a light source that is deficient of a first primary color, a display device to visually present a content using light beams of the light source, and a processing device to receive the content, calculate, taking into account an effect of deficiency of the first primary color in the light source, a metamer of a visual presentation of the content to compensate for the deficiency of the first primary color in the light source, wherein the calculated metamer when presented on the display device substantially preserves color appearance of the visual presentation rendered on the display device and substantially preserves a hue of the visual presentation by means of digital image processing that compensates for the effect of the deficiency of the first primary color on the color appearance, and provide, to the display device, the metamer of the visual presentation to display using the light beams.

Abstract: A system include an light emitter to generate a primary light, a filter to filter the primary light to substantially remove a spectrum energy in a wavelength band, a display device to present visual content using the filtered primary light, and a processing device to receive a visual content, calculate, in view of the filtered primary light, a metamer of the visual content, and provide, to the display device, the metamer of the visual content to display in view of the filtered light.
