Depends if you want contrast or a more blended look with the cabinets.

Take a cabinet door with you when you are looking at the granite slabs. You will soon see that some look better than others and it will be easier to pick a favorite.

cabinets are a lighter pecan (kind of busy) and floor tile is light beige.

What shape kitchen do you have? Take a rough floor plan with you to the slab yard. Have the sales person help you understand how your kitchen would be laid out on the slab so that you know where the seams will be. A wildly veined granite is hard to hide the seams on, so consider this before you choose.
