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.

Please post pictures to show us what you're dealing with.

Option 4. I would not have more than 2 different cabinet finishes. Darker, grounded look for the base and island, with lighter, airier look for the uppers would balance the room.

Hello Diya, Go with light grey or pearl white wall tiles with overhead cabinets. If u want you can go for vibrant colors also, if used in proportion will give the happening ambience for small space. The functionality and store space has nothing to do with color combination. U can go for white ( light color ) cabinets with pop up wall tiles and a small suggestion if u can replace that counter top with light color finished top, that will change the space a lot.
