This paper describes two methods that add a multicolor property to the rainbow holographic technique. The first method simply superposes three rainbow holograms, each of which is recorded in a different wavelength. It generates a three-dimensional, natural-color image in white light. The second method is also a super-position of rainbow holograms but requires only one wavelength in the entire recording process. The variation of the reference beam angle is converted into different colors. The reconstructed image does not necessarily have the original color distribution; rather it gives us a freedom to encode each exposure in any desirable color.
