It's not likely you're going to find an item outside of Delta that exactly matches that color. However, you don't have to have an exact match to install something. Look for other bronze/brass pieces that have a similar color value and choose one you like.

Liberty Hardware has a champagne bronze finish that matches exactly to the Delta champagne bronze.
I'm interested in some Savoy House pendants in "warm brass" but I haven't seen the finish in person yet. I have my lighting appointment (new build) in a few days so I'll update once I see if it all coordinates.

I stumbled upon this where someone reviewed that it matches champagne bronze perfectly

@ dbkstl How did you light selection turn out? I am curious to see if you decided on a pendant to match your Champagne Bronze faucet. I have the same decision to make very soon. :)

I did not end up going with the champagne bronze faucet. But I did find that Amerock does create a champagne brass finish in cabinet pulls/bins that matches the faucet. I ended up doing polished nickel faucet and polished nickel pulls and the Vintage Silver (which looks more brass) Sennett 3 light from Wayfair for pendants. Good Luck! don't have pics yet, but will post when done.

dbkstl,

Did your Savoy House pendants complement or match your Delta Champagne Bronze?

The Haworth 9W 1-Light Cylinder Pendant in Satin Bronze was an exact match

We bought the Delta Champagne bronze Trinsic faucet and found that the Atlas Hardware Champagne hardware matches near perfectly! https://www.atlashomewaresdirect.com/cabinet-hardware/finishes/champagne
