I was going to suggest real B&W film instead, then you can teach her to develop at home too and see the results as it hangs to dry, she might like that, and B&W neg's are much nicer to look at than color ones. Plus B&W has more latitude for error, AND if she gets a lot of "dull" color from the cheaper film, she might loose interest, but B&W is almost always more interesting with the contrast of tones IMHO... just a thought.
