| Title: |
Scrolling Primary Color Changer |
| 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.
