It has a descent lighting. I like bold colors. and this is a living room still in construction. The room has rectangular shape, this is half of the room. There is window on the opposite side of the TV(my back side while taking the above picture). The window size is 6 x 4 feet.

I'd suggest dark red curtains if you need curtains at all -- the windows are beautiful as they are, and I'm not sure whether some kind of blind might not give you the ability to darken the room when you want to. On the wall, if you are real fans of any movies or TV shows, three big posters would be fun. Otherwise, I would still suggest using three pieces of art there of that size, all equal in size and somehow relating to each other. Three floral works, or three works in the same style, perhaps. I think a large plain textured rug in a light neutral from one of the cushion fabrics would tie the space together well. You might also consider a lovely low coffee table on the rug to lay out your snacks and drinks for serious media nights.

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

I've seen a lot of photos and I have come to realise that I really like the pastel/muted color pallete and have also come to know that they are good for small rooms. I really liked nickel grey and silver grey. Do both of these colors also belong to pastel color pallete? I am not able to find a separate section for pastel color pallete on asian paints' website. So it's difficult to find similar colors. Thanks for helping me.
