Well, you can get a full color image from my method this way....

Make 3 color separation negatives by exposing in-camera and developing normally.

Then, take each separation and soak it in a dye solution so that the blue separation gets yellow dye and etc.... You may need to use a mordant or metal salt to anchor the dye in place such that you get a density of about 3.0.

Then run the dye bleach process that I gave above for each of the 3 negatives and it will give you 3 positives.

These, mounted in register, will give you a rather nice color transparency just as a similar method using three color developers and an appropriate set of couplers will give you Kodachrome like slides.
