Thanks for ur advice guys ! Is there any other color advice ? Like brown n beige mix . Will it suit the high walls . I seriously don't have any idea as how to use the color . I tried a green on the walls in Photoshop . It looks totally lame but just want to know how to mix the colors . Any suggestion on how and where to use the color will be appreciated . Like dark color on the wall which has the TV and light color on all the other walls or opposite walls with the same color .. Pulling my hair out !!! I wanted to go for the black sofas only cos of low maintainence . It wil not get dirty soon . The one big thing under the staircase is my fish tank . The one near the wall is the TV . Yes we have fans attached on the walls . Since we have a high roof , we cant use ceiling fans . And the house is not equipped with a centralized AC . I just want a color which will helps me relax and will also look modern .

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

You've got a great space here, and there's so much you can do with it! Do you know what style you're looking to achieve? If you've already got a red and white colour scheme going in your kitchen, you can always opt for this in the living room. Sometimes grey can make the room look a little dark, so it's always worth investing in a white base, and build from there. Maybe change the colour of the curtains to something a little lighter and richer?

Thanks @dream design and @cornerstone. this is my living cum dining room..floor plan is attached below i am having a brown tinted mirror wall on the longer side of the dinning area. 1) which color shade to choose for giving it a rich sophisticated look which will go well with the mirror. I have shortlisted Sonnet as advised in previous comment. What about Morning Glory and Pure Ivory. 2) color shade from Asian paints for ceiling 3 ) also will it be a good idea to paint tv unit wall and/or small wall on the dining side with a grey shade or a different colour ( you suggest) 3) I am attaching the picture of work which is going on.
