Depends on what effect overall you want -- hot tropical feel (oranges and reds) or a bit more toned down? You can take inspiration from pictures of gardens with lime green heuchera or sweet potato -- often paired with chocolatey purple, silvery greens and blues.

Manju, the range is really huge.. You need to start off with your budget and then see what fits therein. For eg. A cot may start at 10 K and go upwards in lakhs... Thanks, Nitin Cornerstone Designs, Bangalore.

two basic issues your room floor is dull is that floor to floor carpet if yes then add a a smaller area rug under your table to get splash of colour, alternatively if you dont want to do that then add some colorful wallpaper behind the sofa. Where you have the table lamp add something taller like a modern floor lamp or a tall spread out palm plant. Take the table lamp and add to a side table if you have one. The second biggest issue is that you have a lovely modern sectional sofa and then you have paired it with a very traditional and very high coffee table that looks like it has marble inlay work done (cant make out clearly). This is not a good pairing. The coffee table is the right size but get something modern and a lot lower, a general guide to this would be one inch to 2 inches lower than the seating height of the sofa. As someone else mentioned an Ottoman that can serve as a coffee table in an alternate colour will also work. Paintings and wall art is something you can experiment with but unless you do something about the coffee table the room will continue to look odd in my opinion. Also some more shots of the room will help us get perspective.

Vinay, Since you have hired a professional, not sure how much of below will make any sense. This is a tall-boi room and the windows and doors height add to it. You have quite a good exterior view with surrounding greenery but the messy grills have kind of killed that view. You may have to always use sheer to hide them and coupled with earthen colored curtains. Plain bland white walls is another thing you may want to reconsider. Without going into too much details, a clean contemporary look for this place would be best suited. The ceiling lighting doesn't seem sufficient for a 14*15 room and I feel there is too much of wood on the ceilings even in the other parts of the house. As of now it looks like a transit place and glad to see this being made a permanent home. Will be eager to see the end results. Thanks Nitin Cornerstone Designs, Bangalore.
