White

would you do a tan or black countertop with white cabinets?

black

the dark stain cabinets would be richer looking and you would have more counter top options, I think. Just make sure that you have enough light in your kitchen to use the dark cabinets and that you are not making this decision based on the paint colour. The paint is lovely but in the long run, your paint will be much more easily changed than your cabinets.
