I have a Moen spot resistant stainless faucet as well and the color more resembles the brushed nickel color. The stainless isn't far off but when I compare the faucet to the brushed nickel air gap cover and then my stainless steel refrigerator it's closer to the brushed nickel for sure.
Thank you for contacting Danco. The stainless steel finish will work best for you.
