I think the white farm sink is fine, but you should look at photos on Houzz of kitchens with off-white cabinets and bright white backsplash tile. It does make the cabinets look more yellow (or sometimes pink or gray, depending on the undertones) in contrast. Some like this look; some don't. I happen to be in the latter camp. Using bright white appliances with off-white cabinets has the same potentially-problematic effect.
