In desire for a change of pace, I've been thinking of contact printing colored leaves or various objects on color paper and either contact reversing them (too bad about the backprints) or scanning. Have people done this frequently before with color paper? I've done it with black and white... Does this seem like something interesting to do?

and any idea on filtration? I assume I'd balance the paper density to neutral grey and then the exposure to black or maybe a stop or two beyond.
