Change out the chairs. Whether at your kitchen table or a kitchen bar like this, chairs chosen as conscientiously as these modernize the look and give another layer of style.
This kitchen, compared with the bathroom above, really shows off green's diversity. This pretty pale color sets a calm tone in the kitchen, so different from the intense energy of the bath. It's not boring, though - imagine the wall as beige or even blue. It wouldn't be nearly as interesting.
I think this cool mint tile arrangement is so pretty and I love how it's extended all along the wall. With different decor, it could trickle into "country" territory, but the addition of the Bertoia-style wire chairs modernizes the overall look.
