ABSTRACT:
An improved color changer apparatus for use with lighting fixtures suitable for performance lighting is disclosed. Each of a plurality of parallel-spaced planar filters are adapted to be moved in and out of the fixture beam by rotation in a plane perpendicular to the beam about an effective pivot point. Each such filter is capable of continuous rotation about its effective pivot point and the filters are so shaped that the leading edge of one filter and the trailing edge of another can be aligned such that no ray of light in the beam can pass through either both filters or neither one.
