We need to replace our built-in microwave, wall oven, dishwasher, and gas stove top. I have never liked stainless, but our new-ish fridge is stainless (on a different wall from the oven/microwave but on the same wall as the dishwasher). I love the new black stainless and/or slate colors. Could we mix traditional stainless and the newer black stainless/slate in the same kitchen? Anyone seen or have photos of kitchens with these mixed metals? Thanks!
