Black and white is easy to describe if hard to do.  Etch it on glass or 
something.  Color is hard because dyes tend to degrade over time, 
especially when exposed to light, and it may be hard to get good color 
rendering with whatever you can find that's stable for as long as you want 
it to be, although you could always etch three slides and combine red, 
green, and blue light on a screen.
