Reflection gratings are constructed with red(647.1nm), green (5l4.5nm)and blue (488.0nm) laser beamrespeotively using quasi-panchromatic photopolymer plates. The curves of percent transmission versus wavelength are given. Using subtractive films, colour reflection holograms are recorded with red, green and blue beam from Ar+-Kr+ laser simultaneously. Chromatioity coordinates and colour fidelity of colour reflection holograms are discussed.
