Claim:
A display comprising: a plurality of pixel-generating elements, each pixel-generating element comprising: a light conduit adapted to allow light from a light source to pass at least from a first side to a second side of a series of controllable filtering elements; the series of controllable filtering elements comprising: a first adjustable light absorbing tilter adapted to adjustably absorb a first set of visible light wavelengths from light passing through the light conduit to produce a first filtered light; and a second adjustable light absorbing filter adapted to adjustably absorb a second set of visible light wavelengths from the first filtered light, the second set of visible light wavelengths including at least some wavelengths that differ from the first set of visible light wavelengths, each of the first adjustable light absorbing filter and the second adjustable light absorbing filter adjustable to a substantially transparent state, and the pixel-generating element adapted to generate a viewable pixel having a color adjustable at least between substantially a color of the light source and a color corresponding to the light source as modified by at least one of the first adjustable light absorbing filter or the second adjustable light absorbing filter.
