Lippmann color holograms are obtained by combining three component holograms recorded in different materials. In this technique, a dichromated gelatin plate coated with laboratory gelatin, is used for the blue and green components, while an 8E75HD plate is used for the red component. Ways to obtain high diffraction efficiency and to control the reconstruction wavelength are discussed for each component hologram. On the basis of these results, a Lippmann color hologram of a diffusely reflected object is recorded, and a satisfactory result is obtained.
