I did about the opposite of kjo_tx! I did polished nickel cup pulls and knobs and stainless/brushed nickel for my faucet, soap dispenser and water faucet. I like the warmer look of nickel but my chosen hardware in the brushed looked kind of lifeless to me and seemed to blend into my stainless appliances a bit too much for me. I did choose big cup pulls though so that also contributed. Kjo makes a good point with fingerprints. I find that to be an annoying feature of my pulls but I couldn't help myself and wanted some bling. Wiping them off isn't that big of a deal but my previous brushed hardware required no maintenance. I didn't choose a polished faucet because I was concerned about water spots and tarnishing. As it turns out my stainless faucet shows water marks so it's not completely maintenance free. I think my previous faucet which was also stainless didn't mark up much so it might be different between brands. I think nickel would be really nice for your space since it's a warmer white as opposed to chrome. Either could be really nice. I also think brass could be really pretty. I recall seeing a picture of Kate Spade's kitchen with all brass on white and thought it was gorgeous - could work especially since your appliances are white. I wouldn't choose oil rubbed bronze because I think it'd really stand out too much. It can look great with dark counter tops in my opinion but it's a bold look with paler counter tops. Best of luck! Post more pics!

I always thought all the metal finish in the kitchen have to match but it turned out fine when I mixed them! I always like everything matchy matchy. But not in this case. I have all ss appliances (fridge, hood, dw, ovens, and thin ss trim on my cooktop), my knobs/pulls, peninsula pendants are polished nickel and the faucet/instant hot/disposal buttons are chrome. I guess since those items are not close to each other makes them fine!

Faucet & cabinet hardware are a warm brass

I think in a kitchen polished nickel looks lovely. But I think polished nickel on a white built-in in the living room would look too "kitchen-y" if that makes sense, which is why I like the idea of black. My preference for our new house for a metal finish was antiqued unlacquered brass, but I was at the wrong end of the trend and it was either impossible to find or impossible to afford, so I chose flat black where I could, which I've never had before but which I quite like. It doesn't seem to be all that popular either, so I did make do with some dark bronze or ORB, especially for light fixtures where you're not close enough to see the finish -- not a fan of the living finish either, plus I also don't like the cheaper finishes with the copper showing through, or the flat brown that's supposed to be ORB lol.
