The black sofa could be considered a neutral, and therefore will go with just about anything. Do you like the white and gray, or are you looking for color? Bright colors? Subtle colors? Also with a baby I would surely want an area rug for her little knees. In this first picture you can see pops of red were added for color: [houzz=https://www.houzz.com/photos/2007-aso-decorators-showhouse-and-gardens-contemporary-living-room-atlanta-phvw-vp~26704] In the second picture, a monocrhomatic color scheme with a soft area rug: [houzz=] And in the third picture, yellow was added for interest: [houzz=]

Don’t use too many colours. From the colours you’ve provided,BM Chelsea Gray and Martha Stewart Glass of Milk should go together and look good on the contemporary design of the bungalow.Something like the following pic :- Pic courtesy (Pinterest)

I select these colours with the help of other houzzer and expert professional advice and discussion. I also got help from colour paint catalogue. Is it looking good or not? Is there any problem with these colours and their combination. Please guide me in this regard.

I have pretty much the same colour combination except that the upper cabinets are in silver... also i went for black granite countertop as white is difficult to maintain in our Indian cooking conditions with usage of oil, turmeric and spices....if your budget permits and you can maintain white marble it does give a very sophisticated look...
