A color changer system mounted at the light beam emission end of a luminaire. The system includes a support frame secured to the housing and disposed transverse to the beam, a plurality of iris units each having a plurality of colored, translucent leaves rotatably attached to the support frame, and a circular control plate rotatably mounted to the support frame and having a control slot in which a thrust pin of each leaf is slidably movable and a control handle. The support frame and the control plate each have circular apertures with centers that are aligned with the beam axis. When the control plate is rotated, the leaves of each iris unit open or close in response to pressure against the thrust pin so as to control the coloring of the light beam. The leaves move inwardly from the periphery of the light beam towards the beam axis towards a closed position or move away from the beam axis so as to intercept all or a portion of the light beam to color the portion of the light beam passing through the intercepting leaves. The leaves of each iris unit each have a different color from the leaves of the other iris units, with the colors preferably including the primary colors of the spectrum. Mounting portions are connected to the rims of the translucent leaves. The leaves have inwardly extending walls that are aligned in the closed position of the system. The walls can be either linear or curved.
