There are several methods to introduce false colors into a gray level transparency using three primary colors. We emphasize here methods which makes use of the multiple scattering process inside the film. Based on this it is possible to obtain simultaneously the addition of a positive image, a low contrast reversed image, and a pseudo reversed image. This method works in real time, increases the color range variation of the gray levels, has a good continuous heu variation, and furthermore it has a low-cost implementation.
