1. A system for producing images comprising narrow bandwidth colors that are selectively filterable by users, the system comprising: a light source; a plurality of pixels, each pixel in the plurality of pixels comprising a plurality of narrow-passband filter elements and at least one intensity control element; and a control mechanism configured to display an image by selectively instructing the at least one intensity control element to pass a first intensity of light in a first narrow passband of a first narrow-passband filter element of the plurality of narrow-passband filter elements and a second intensity of light in a second narrow passband of a second narrow-passband filter element of the plurality of narrow-passband filter elements, wherein each of the first narrow passband and the second narrow passband have a bandwidth that is less than or equal to 50 nanometers, wherein the first narrow passband is associated with a first narrow bandwidth color and the second narrow passband is associated with a second narrow bandwidth color, wherein the control mechanism is operable to adjust a center frequency from being within an emission spectrum of the first narrow bandwidth color to being within another emission spectrum of the second narrow bandwidth color, the center frequency being associated with a center color, and wherein the first narrow passband and the second narrow passband are selected so that the first narrow bandwidth color and the second narrow bandwidth color can be interpreted as substantially a same color by a user.
