Are you actually located in India as is indicated when I "clicked" on your name. Styles may be different from US.

A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

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

Hi,  Go for Jet black granite for counter top. It would look classy with your white ceramic wash basin and beige wall tiles. And go for above counter wash basin.
