I've created type 2 PICTS (color Quickdraw) programming in MacFortran 020 and
Absoft's MPW Fortran, and copied them to the clipboard, and they paste into
Word with some color left.  The palette might not be the same, though.  The
colors stored in type 2 PICTS are RGB numbers: three 2-byte integers for Red,
Green, and Blue components.  When the Mac tries to draw a color PICT in a
window that does not have the right RGB's in its palette, the colors are
approximated; I think the algorithm picks a best Euclidean norm approximation
to the RGB values.

	I have also saved color PICTS in PICT files.  I can open these (minus
color) in MacDraw (1.9.5), but not if they have text in them.  I think I am 
putting the text in the file properly, with PicComments, but it still doesn't 
work. Opening my color PICTS in Cricket Draw has always been slow or impossible
  It could be my version of Cricket Draw doesn't use Color Quickdraw, but the
old-style color that existed in software but not hardware on the original Mac.
That could have something to do with your problem, too.

	I hope this helps.
