Preliminary results of full colour reflection holograms recorded in an acrylamide based photopolymer layer at 633nm, 532nm, and 473nm are presented. Recording material is sensitised to three recording primary wavelengths. Reflection holograms are recorded using a combined single beam of RGB wavelengths, are spectrally characterised and compared with the recording wavelengths using chromaticity diagram. An object of additive colour diagram was recorded. The shrinkage effect of this recording material on reconstructed wavelengths is also discussed.
