A color filter plate includes a continuously-variable dichroic filter coating constituting a variable band-pass or variable band-reject filter having a spatially-modulated variable-density pattern formed in the coating, and provides continuously-variable hue and saturation characteristics along separate gradient axes. A color filter assembly includes a variable band-pass and a variable band-reject filter mounted in a co-planar arrangement, providing a continuous range of color filtration for spectral and non-spectral colors. A color filter mechanism includes a color filter assembly having either a rectangular arrangement or a circular arrangement of co-planar, continuously-variable band-pass and band-reject filters mounted in a motorized carriage. One mechanism provides two-axis translation of the rectangular color filter assembly while another mechanism provides translation and rotation of the circular color filter assembly. A light projection system comprising a lamp with a reflector and a lens includes a color filter mechanism having co-planar, continuously-variable band-pass and band-reject filters supported by a motorized carriage mounted in a region where the beam diameter is small.
