Blightly,

Your experience with color negatives matches mine with color negatives: color is troublesome.

But my experience with printing color slides on Fuji Type 35 or Kodak Radiance is very different. Once the filter for the type of paper is established (it's typically 5-10 of two colors, ie. 10C5Y for my current box of Fuji Type35), then all prints are made with that filter. Of course, I change it for artistic reasons, but if I want a print to match the slide, I print it with one setting for that box of paper and find the results match quite well if I don't mess up the exposure.
