We just finished a pine table.  Applied a ZAR Clear Wood finish (poly) and
turned yellow...much more yellow than we would have liked.  

Any suggestions on toning it down....Hate to have to have to remove the
clear 

Thanks,

Jeff

Next time make it out of white pine ,that yellow pine will turn on you
in an instant.
Seriously ,hatever youdo is going to make it darker short of painting
it white . So my suggestion is to strip it [and i know thats not what
you want to hear ] and finish it with a true clear finish ,such as a
water white varnish as sold by Sherwin Williams [no asociation ]

Sounds like you have used an oil-based finish on it and these have an
amber tint to them.  Different oil-based varathanes, polyurethanes, etc.
have a different amber effect by manufactures but all will amber your
pine to some extent, some more than others depending on the brand name.
If you want a clear finish, stick with Flecto Diamond Elite, a
water-borne varathane that won't change the colour of the wood.  The
wood will change colour (patina) in time due to aging (like us) but the
Flecto Diamond Elite will remain clear for the next 20 years.

Other than stripping it back to bare wood or painting it a light colour,
there isn't much you can do at this point.

Clear wood finishes can impart amber hues - you have choices:
A. strip & resand, then use a water-based poly finish,
   which tends to be very cool, not amber at all.
B. If A is a pain, consider reversing the coloration with
   a toner.  Without going into color wheels and all that,
   to un-yellow something you need to apply a purplish
   toner.  Sounds crazy, I know.

   Spray an extremely dilute purple toner over the work.
   Repeat spraying until to have cooled the color back to
   what you wanted.  If you can't beg, borrow or steal spraying
   equipment, then it's stripping time.  Strip really soon,
   before it the finish cures any more than it has already.

Best advice - in the future, test finish a scrap piece of wood 
first to make sure you're gonna get what you want.  Saves a lot
of grief.

More information on this see either Ian Hosker's "Complete 
Woodfinishing" or Bob Flexners "Undetanding Wood Finishing".
