| Title: |
Scrolling Color Changer |
| Abstract: |
A combination color filter having at least two dual-hue color-changing
absorptive substrates. A desired hue and saturation is achieved by using
light absorbing gels for a plurality of selected hues, preferably the
three subtractive primary colors. The unique arrangement of transparent
part, saturation parts and continuously graded saturation parts allow fast
color bumping between any two primary colors without flash of white and
presence of other intervening colors.
