I have granite, a black with gold and green flecks and white cabinets. Mexican tile floors, 12 x 12, that are mostly a beige but because it is Mexican tile, the tiles vary from one to the other which I like. If I were doing dark cabinets, I would probably do a lighter counter colormaybe something with a little gold and brown streaking to match the cabinets. We have a small galley style kitchen, if I had a bigger counter area or an island, I would try to find a large piece so there are no cuts. Marble can also be beautiful. And around here, Chicago area, polished concrete countertops are popular. For flooring, it’s very personal. I used to have wood and changed to tile when we redid the kitchen about 8 years ago. Cork is good and a little softer but durable. I think high end linoleum is even coming back. I went to a high quality tile store and used their design services for my kitchen and bathrooms when we rehabbed them all about the same time, He really helped me come up with some great ideas for kitchen. back splash, showers and floors.
