I used to fool around with it too. But it was
too much work. So I just wrote a bunch of color
tools that don't care whether color decomposition
is turned on or off and I use those. I haven't
set the color decomposition keyword (or even looked
to see what it is set to) for well over a year now. :-)

Programming itself is too hard. There really should
be some other way. I hear tell there is a pretty good
book around about IDL Programming, but I don't have the
time to read it, and I can't remember the author anyway.

You will probably have to modify something like the VELOVECT
procedure. Everywhere it is using a PLOTS to draw the arrow,
you might want to substitute an ARROW, /SOLID command. It will
be a bit slower, of course, but it will probably look good.

Cheers,
