What kind of look are you going for? If you want classic, you could try one of the blacks like Black Galaxy or Absolute Black. If you want dark and sparkly but not black, there's Uba Tuba. If you like the dark green of Uba Tuba but want a little more variation you could try Verde Peacock. Or if you like blue better you could do the Blue Peacock.

Do you prefer a light and airy look? You could try a light Virginia Mist. Or a soft color like Tropical Green.

Do you want to make a statement? Then you could do one of the Jurassics or Van Gogh.

So far you have a neutral palette. What's your price range, and what do you want your kitchen to look like?
