​If you like the idea of mixing metals, just make sure that the mix looks intentional instead of haphazard.  To make your design of mixed metals look intentional, choose 2 or 3 metal finishes and use those finishes in at least 2 or 3 areas within the space.  That way, each metal finish has coordinating partner in the same space.   Take a look at the 3 photos below.
Let’s talk first about metals. As a general rule, I like to keep the different metals in a kitchen to no more than two. If you have stainless steel appliances, that counts as one metal. So that leaves one other metal you can bring into a kitchen. If you’ve got brass light fixtures, that’s your one other metal. Your new hardware should be nickel or brass.
