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 .

I like the ceiling. I think the hanging lights are too fancy and distract from the ceiling decor. A simpler light would look better or sticking with the canned lights you have. The walls have too many big, black things on them. It's hard to tell if they are windows with shade --- in which case I'd pick something lighter, perhaps to echo the ceiling, TVs (how many do you need?) or what. I'd consider a big piece of statement art in the place of at least one. If you're on a budget, get a large, high quality photo in the right colors, you can take it yourself. Sepia and black architectural might work. I like more color and more natural light. You may have closed the shades for a better picture, so it's hard to comment on the light, plus windows are a feature of your room, not exactly a decorator's choice. I would consider how to get a few small pops of color in, pillows, flowers, candles, maybe even a runner rug along the right wall. If you are doing this as part of a portfolio, the entire ensemble would look more welcoming with a few touches like someone lives there. Something on the coffee table, for example. A few books and a candle. A tray with tea things, a vase of flowers or basket of fruit. Pick one or two things and make it composed. You see this a lot in designer Houzz photos. Here's an example, you note this picture would be a lot more stark with an empty table: https://www.houzz.com/photos/21-house-contemporary-living-room-san-francisco-phvw-vp~60642

I would use the greens from your bedspread. Since you have green in the bedspread, and brown and white tiles, those 3 colors need to be your focal point. So I have painted your wall a bright olive green ( the darker color in your bed spread) and the ceiling either a brown to match the tile or a white to match the rest of your ceiling. then or I think this last one is a little tamer . But you should be able to paint over the tile. WHAT kind of tile is it? If it is ceramic you can paint it. Here is a link about how to do it: https://www.sherwin-williams.com/property-facility-managers/education/styles-and-techniques/sw-article-pro-resuscitateold.html

Thanks everyone, I'm planning to get my floor tiled up soon, and then later the whitewash. So before all that, I wanna do away with the construction part, if required to transform this hideous corner. I had the roller blinds in my mind to hide these iron windows, but I will also look at options for changing them windows entirely if budgets allow. I might have to use some false ceiling work as well. Posters, I don't think can find space here, but a lounger sofa-bed is a surething with some nice lights. Please do share some pictures of the lights and loungers and floor tiles if you may, for suggestion. I'll be obliged. Thanks again!
