try doing a fume patina with ammonia...same stuff you clean with.  here's
how--get a vat of some kind that the piece will fit in.  put bricks in the
bottom of the vat.  pour about a cup of ammonia into the bottom of the vat.
 place your piece on the bricks.  seal the vat with a tight fitting lid or
plastic.  (seal it well).  leave for a couple of days and then check it.  you
should get  a green and blue patina or green/blue patina.  the one problem
with patinas in genreal is that they are fugitive and you need to seal the
patina.  sealing it will bring the coloration down quite a bit.  so you may
want to try using a water based paint that you can wash over the patina
(gently)  to give it a more permanent coloration.

good luck,
