What about just bringing the taupe/grey into the kitchen? Keeping the same color could make the area look bigger. I don't usually like a lot of blocks of color, it chops the rooms up. And, when you sell the house, the more colors, the more instances of people not liking one or more of them.
My kitchen cabinets are a dark honey oak with brass knobs. My appliances are black, my floor is terra-cotta, my counter is granite (grays, caramels, and creams with a terra-cotta vein running through it). I painted the walls with a double shearling roller. Using a split paint tray - one color a beige, the other color a very light shade of the terra-cotta. It almost looks like Venetian plaster, its a very subtle technique and overall looks like a peachy beige. It brings out the golden tones in the cabinets nicely.
A suggestion for knobs/fixtures - brushed nickel. It's warmer than chrome or stainless. And the brushed finish is easy to care for.
