Hi there, did you mean to attach photos? I don't think they posted. I know this is from a while back but I'm interested to hear what you ended up choosing.

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.

I have just planned the above color scheme for my new home .Not yet completed and I have to put an order for granite . ACTUALLY I like white counter tops but marble is not a good option. Should I choose WHITE GRANITE OR JETBLACK TO GIVE A CONTRAST OR SOMETHING ELSE?.

Which area it is? What business you do? Depending on that we can discuss. In general combination of wooden shade and white can work for most of the places.
