Yes, spotread is the right command...but that's *very* yellow for a paper. It's 
the sort of thing I'd expect from aged newsprint. If that doesn't describe what 
you sampled, something else is amiss.

I don't think Gimp supports anything other than eight-bit RGB values. Sadly, 
there is only one good tool for manipulating other than eight-bit RGB files -- 
Photoshop -- and soon, if you don't already own a copy, your only choice will 
be to rent it.

But if you're just wanting to look up RGB values for a Lab or XYZ color in a 
particular color space, that's what Argyll's xicclu is for.
