This might sound like a very "simpleton" suggestion, and perhaps not what
you had
in mind, but from working in Photoshop, I've noticed that raising the
contrast of an image seems to increase the color SATURATION of all the
colors. This could be duplicated in POV, though not quickly, by actually
changing the   pigment {color rgb}   values of each and every OBJECT!!!  A
chore, I know.  In other words, if an object has rgb <1,.5,.5> as a reddish
color, then a more saturated color would be <1,.3,.3>.  Then, of course,
also lower the AMBIENT lighting of each object. The rendered scene might
then *appear* to be of higher contrast. Worth a try?
