Google galvanic reaction between two dissimilar metals.

At the present, I am working on inside the house. Years ago I switched from gate valves on all my water connections(including many outside ones, to the barn/shop/for watering, etc.) to ball valves, as they leaked less and held up better. But I am still not satisfied with the connections from brass to pvc. I have two sources of water to the house, city(utility) water, and also lake water. So I use the ball valves as on/off valves. Now that I am finishing off the basement and covering/enclosing the area where all the pipes/valves converge, I need to make sure there are no slow drips. Robert

Oh, no! It's easier than that! It'll look good if the mixture of finishes isn't all mushed together. Don't do a bank of cabinets with brass knobs and a bank with stainless, one brass faucet and one stainless, a black range with brass and stainless knobs and copper pulls on stainless appliances everywhere else. A hood is unique in a kitchen. It shouldn't be out of step with the stove (not Italian art glass over vintage Chambers), but most stoves will pair well with most hoods. And most hoods will go in most kitchens. Natural cherry should go with either copper or brass. Cherry is kind of orange beige. Copper is reddish with a little orange in it. Brass is yellow with a bit of red in it. In other words, all are in the yellow-red continuum. Natural oak is either yellowish or reddish. Uba Tuba is green. Stainless Steel is gray. That gives the middle ground to the cool colors, and lets the hood pick up the tones of the upper cabinets. Good, since it's an upper item itself. This sounds organized, with good contrast accents, and good value variation. In other words, I think the hood should look just fine, and that the colors you've chosen for the kitchen should look really good together. My opinion? Don't use copper or brass knobs. Let the hood be it's own thing. ORB or another antiqued bronze would be okay if you want a warm tone, but brushed nickel might be better. Give you a little punch and shine.

My primary concern would be that the champagne bronze faucet and the (cant remember now) color name of the pot filler are two entirely different colors/metal finishes. In my last kitchen, I had flat black (rasped iron) hardware on cream inset cabinets with stainless appliances (range had brass trim) and my tap and pot filler were both uncoated brass. The lights were ORB because that was the lighting scheme for the entire house. The cabinet hardware was black because all the hardware in the house was black. The faucets were just because I love *real* brass and it looked great.
