I am trying to decide on color of kitchen hardware. I have decorators white cabinets, a blue/gray island, brass pendants over the island, stainless appliances, and brushed nickel faucets on stainless steel sinks. I know we can mix and match metals, but have no idea whether to choose Brass, brushed nickel or polished nickel hardware. I don't want everything competing with each other. Any suggestions? Thank you!
