Hi sanjali, sorry I didn't see this post earlier - were you able to solve this design dilemma yet? How'd everything turn out?

A combination of Offwhite, Beige Upholstery and dark shades of wood would look good. Provided you keep the wood minimal . The floor can also be a similar shade of wood . Remember whatever you do, make it look rich and elegant, only then will you be able to pull this look off. I am assuming the your ceiling is considerably high as well. Paint the walls and ceiling in offwhite shades with only the feature wall grey

So I am planning to do something like that in the picture. I really liked the use of the emperador marble and the balancing of the colours. In the second picture, I have selected the emperador for Wall as shown in picture, the light ones will be for the next three walls and the third tile will be for the flooring. I hope it'll look good.

I prefer shades of brown ..blends well with all colors.
