Sorry to hear that. What finish were you trying to match?
Usually its best ti use the same brand name when trying to match a finish, such as a Moen faucet to match a Moen towel bar or towel ring.
That is because everybody has their own technique of making their products.
I wonder if the finish on your new American Standard faucet is doesn't match because the other item you're matching in not made by American Standard.
You should be able to return it if it hasn't been installed in any way and you still have the original packaging.
The return items page has complete directions that make it fairly easy to send items back.
Good Luck!
