Frankly, I'd do it with light control. You know, good old fashioned
reflectors to light the rusted artwork. I suppose you could put a skylight
filter on. It wouldn't put any noticeably unacceptable color casts on rust
or grass, but the advantage may not be noticeable either. Rust is a reddish
color and green is, well, green. Not having any more information than you've
given, my imagination tells me to expect good color contrast to begin with
if the colors are well saturated. Unlike black and white, a red object and a
green object that both emit the same amount of light (adjusted for the eye's
varying sensitivity with color) will have great contrast despite identical
levels. The same objects might be indistinguishable to B&W film. If you want
contrast, pick a high saturation film and perhaps overexpose just a little
if print film, underexpose just a little if slide film. Hell, Shell (rhyme
not intended) experiment! Play around a little!

I know how to control contrast and tonality with B&W film, but how does one
do it with color? For example, there's a piece of artwork that I'd like
to
photograph. It's rusted metal and the background is green grass. I'd
like
to photograph it in such a way that the grass is much darker and the art
work is lighter, resulting in more contrast between the two. Is this
possible?
