Abstract
Color-changing apparatus, and an associated method, for a lighting assembly. One or more dichroic filters are selectably positioned in the path of a light beam generated by a light source. A positioner supportively positions the dichroic filter and effectuates its translation into and out of the path of the light beam. A set of dichroic filters, each separately supported by a separate actuating positioner permits a combination of dichroic filters to be combined to cause the light color of the light beam to be of any desired color.
