Zusammenfassung:	A luminaire and light source are provided. The light source includes first (20), second (30), and third (30) arrays of light emitting diodes (LEDs) and a beam combiner (52, 54). The LEDs of the first (10), second (20), and third (30) arrays of LEDs emit beams whose optical axes are substantially parallel. Each of the first (10) and second (20) arrays of LEDs produce light of two colors. The third array (30) of LEDs produces light of a single color. Each of the arrays of LEDs includes a plurality of zones, each zone spatially separated from other zones. Each zone of the first (10) and second (20) arrays includes LEDs of two colors. The intensities of the LEDs of each zone are controlled independently from the LEDs of other zones. The beam combiner (52, 54) combines light beams from all three arrays (10, 20, 30) of LEDs and produces an emitted beam of light (56) and maintains the optical axes of the light beams as substantially parallel to each other in the emitted beam of light (56).
