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.

There are probably 5 million kitchen photos here on the Houzz website. What I would suggest is looking through some of them to get an idea of what you like. Also posting photos of your space (jpeg format) helps visualize your options. We could just randomly throw out suggestions but it may or may not be what you want. Good luck!

If you will like to go little different than Indian / traditional one, mint green colour is in trend and goes well with brick colour walls. Looks good if you have white appliances, crockery and some other elements that are visible with it. (Sourced from google images) https://goo.gl/images/Wyu1kR

Hi Chayya, For a contemporary style kitchen, you can go for a monochrome theme for the entire kitchen like a matt grey with brass seamless handles. It can be a good option with a white backsplash. You may also consider combining brown patterned finished shutters with lacquered white finish for a clean, contemporary look. Hope these suggestions help you
