A lighting system including a light source, a means of collecting and focusing
light from the light source, an aperture, a filter module containing at least one
color filter, and an image lens. A light beam from the light source is focused
through the aperture to define the image to be projected. The aperture is positioned
upstream of the color filter, with the filter and the image lens being deployed
in the area of the light beam where the diameter is at a minimum. The filter elements
used in the filter module are two stage filters, having a first stage for a pastel
level of a particular filter color, and a second stage for a saturated level of
the subject color. Each stage has a gradient segment and a solid color segment.
The result is a filter element with four regions that blend into each other.
