We have tile countertops in our kitchen right now, courtesy of the last owners. I think that they're pretty, but I'll admit that they do look dated. We are thinking of upgrading all of the counters to granite, as we are also adding some counter space in another part of the kitchen right now. What I am wondering is whether one color/type of granite is more desireable than another when it comes to resale? Black or dark-colored granite seems to be what I see the most in model homes, but I don't know if that means anything. Is there a general concensus on this
