Abstract
A color changing apparatus adapted to be installed between the reflector assembly and front barrel assembly of a theatrical ellipsoidal spotlight. The color changing apparatus includes a housing for connecting to the spotlight components. Contained within the housing are a plurality of color filters, preferably dichroic color filters, serially arranged perpendicular to the light path. The color filters may include constant or variable density patterns of any desirable color and are transported into the light path to effect a change in lighting conditions. The color changing apparatus is also preferably equipped with a control system enabling remote actuation and control of the system.
