A color hologram recording medium 2 includes volume hologram recording mediums 14R, 14G and 14B for diffracting light of wavelengths different from each other. Reconstruction patterns 1R, 1G and 1B of the volume hologram recording mediums 14R, 14G and 14B are recorded so that the reconstruction patterns 1R, 1G and 1B are reconstructed at reconstruction positions different from each other. Thus, the color hologram recording medium 2 can have a wide variety of designs and artistic characters that the recorded color reconstruction patterns vary depending on watched directions.
