1. A system, comprising:
- 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.

16. A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:
-
receiving, by the processing device, a visual content to be displayed on a display device, wherein a primary light associated with the display device is filtered to substantially remove a spectrum energy in a wavelength band; calculating, in view of the filtered primary light, a metamer of the visual content; and providing, to the display device, the metamer of the visual content to display in view of the filtered light. - View Dependent Claims (17, 18, 19, 20)
