1. A light display comprising:
at least one of a color filter or a color reflective surface;
color emitters included in the color filter or the color reflective surface, and including,
first color emitters configured to emit, upon exposure to a light source, visible light at a target color in response to absorption of energy across a first band of wavelengths, and
second color emitters configured to emit, upon exposure to the light source, visible light at the target color in response to absorption of energy across a second band of wavelengths, wherein a mixture of the first and second color emitters comprises a component of a color reflective surface of the display, and
wherein light intensity observable at the target color is enhanced relative to reflected white light without emission from the first and second color emitters.
