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

You can try shades of teal & white in maybe floral,Paisley or a pattern that you want to try in incorporating with the theme of the room. Since your furniture is brown ,please try fabrics with white,teal and shades of brown as well...Go for a cotton/ raw silk fabric rather than heavy material drapes.Keep it floral and summery.Teal is associated with summer and ocean.Thanks.

Does it suit only particular decor??

Namrata, If your intention is to let the light in and yet maintain the privacy then vertical blinds would be one of the good functional solutions. See the attached image for your reference. Note in your pic at this angle it looks like the TV unit ledges have been taken to the far end of the window wall. This shall pose issues with your curtains/blinds as well. We mean to say your curtains will not close on the right hand side completely.\ Hope that this is not right. Let us know if it is. Thanks Nitin Cornerstone Designs, Bangalore.
