ABSTRACT:
A color changer (20) comprising a component hue saturation filter (30) including an elongated flexible substrate (32) having a surface with a gradient axis (GA) and which includes a graded portion (G) supporting a uniform concentration of a selected hue filtering material (50) distributed in a continuously graded average density in beam-size areas around points along the gradient axis. The component hue saturation filters may be embodied in separate substrates positionable in parallel planes to be intersected serially by a beam of light. Alternately, dual-hue filters (68) may be formed by two primary hue component filters embodied in respective substrates each also embodying duplicate third primary hue component filters producing the same effects. Saturations of each selected hue of light appear evenly distributed in the output beam without the need for color components to be further commingled.
