Claim 228:
229. 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 at least one of the first and second color emitters comprises:
(i) a dielectric up converter including at least one of Y2O3, Y2O2S, NaYF4, NaYbF4, YAG, YAP, Nd2O3, LaF3, LaCl3, La2O3, TiO2, LuPO4, YVO4, YbF3, YF3, Na-doped YbF3, or SiO2 or alloys or layers thereof, or
(ii) an upconverter including at least one of Tm3+ doped flourozirconate glasses, LuPO4:Yb3+, Tm3+, and YbPO4:Er3+ nanocrystals, tellurium and germanium oxides, tellurium and germanium oxides doped with at least one Tm, Yb, Ho, Er, or Pr, Yb3+ doped BaZrO3, Nd3+:Cs2NaGdCl6, Nd3+, Yb3+:Cs2NaGdCl6, Nd3+ and Ho3+ co-doped-based ZrF4 fluoride glasses, Tm3+/Yb3+-codoped TeO2—Ga2O3—R2O (R=Li, Na, K) glasses, and metal-to-ligand charge transfer (MLCT) transition materials, and MLCT transition materials including [Ru(dmb)3]2+ (dmb=4,4′-dimethyl-2,2′-bipyridine),

wherein light intensity observable at the target color is enhanced relative to reflected white light without emission from the first and second color emitters.
