This is the crux. Can I make a "color vector" that has a length of 2
(or 3 or 5)?. If not, is that because of limitations with IDL, or
because of limitations to the TIFF spec. I've given the spec a
glance, and I can't see that the palette must be 256 colors.

Yup, so now I'm looking for alternatives.

No, that's exactly right, if your palette has 256 colors, load them
all. But I really don't want a palette with 256 colors.
