A high contrast front projection system includes a reflective screen configured to reflect light in a plurality of narrow-band frequencies, and a projector configured to emit light substantially in the narrow-band frequencies. The narrow-band frequencies are centered on red, green, and blue colors such that the reflective screen reflects about 90% of light at the plurality of narrow-band frequencies, and less than 10% of light at other frequencies.
