Black and white images have clean solutions.  Unfortunately, color
images don't -- color film, especially older film, probably already
has faded quite a lot and will fade more over time.

One solution comes to mind, from a very old book about photography
that mentioned color images done with black & white film vian an
interference scheme.  Film mounted on a reflecting background, mercury
originally -- interference fringes in the (thick?) emulsion...  That
would be as good as silver black&white film...
