Actually, the eval_pigment function returns just three. (I've always been
curious why it wasn't designed to return all five.)

Another possible reason for Nekar's problem might be the unexpected behavior of
color 'dot operators' (if he's using them.) The "Common color pitfalls" section
in the documentation gives a good rundown of what to watch out for. (Although
I'm not sure if the eval_pigment result constitutes a true COLOR, in the sense
of an implicit "rgb" color; it's a *function* of a color. But I use the
documentation workarounds with it anyway, just to be safe.)
