You are going to have to leave your comfort zone on this one. Walnut is "brown", you have "pink" as a counter top. I would suggest going with another version of the colours already in the room. you have gray/beige and white. I would hesitate going white...but it can be done. You can move into the grays and be very happy (it would look very modern) or you can move into a beige that holds a hint of pink in it (not pink...but a blush of warmth). Or you could go really wonky and add in something like a brushed stainless steel look to the cabinets and have it go "space age". There are specs of blue/gray in this counter top. The next think to look at is an "ashwood" or dark gray wood presentation that has some blue in it. It would lighten the space yet still add drama that dark cabinetry offers.

add some pictures of your space for better suggestions

Hello dopcam, Compliments ! Its a great open kitchen. Please see if you like Century Almond Ivory 127 LU and Graphite Grey 238 LU combination. It will look awesome in this kitchen. As the sink is on the right wall it's not recommended place for an island. You may see if you like a standalone island . Thanks, Nitin Cornerstone Designs Bangalore

yes , a pure white kitchen will look great , the tiles will be the highlight of the kitchen.The mixed colours of the tiles , pure white cabinets and the Black granite will look Superb!!
