If you will like to go little different than Indian / traditional one, mint green colour is in trend and goes well with brick colour walls. Looks good if you have white appliances, crockery and some other elements that are visible with it. (Sourced from google images) https://goo.gl/images/Wyu1kR

Hi Anirudh, As budget is 40k, few options come to my mind without major changes to the entire setup you already have. Hope this would be of some help; The wooden linoleum flooring is not looking that great. you can think of removing it if that is an option. You can add a rug to the living room, synthetic rugs come is great variety and are inexpensive. You can go for a beige colored rug, plain or patterned. The first pic of your living room: Without replacing your Sofa changes you can make; 1. change the curtains. To create length and make room appear big and high up..Go for sheer curtains in white/off-white (something similar to the wall colour). Hang the curtain rod high up with width a little more than the window's (exact width of windows don't look so good). 2. Sofa Cushions: Replace the cushion covers with mix of - White(patterned-any small pattern would work) & Bright Blue color plain or patterned covers. Pic 2: Showcase: If you are not too emotional about that showcase, you should get rid of it. Instead hang Huge painting in neutral palette (nothing very bright) to cover it up. Any stretched Canvas paintings will cover up the showcase entirely. Those single picture frames should go away and so does the wall hangings. Pic 3: 1. BookCase: Buy/Diy a bookcase on top of the existing one...such that it touches the ceiling. You can completely get a new book case with wall to floor height if you please. Please don't crowd the bookcase, instead add a mix of books and some stopper or picture frame or decorative items. 2. TV Unit: The TV Unit is bulky and adds nothing to the room. Instead buy a simple one with drawers. 3. The wall clock is too small for the wall. Buy a bigger one so that it doesn't look too tiny with TV. You can go for a colored wall clock, like something in GREY or TEAL BLUE, provided your wall if lighter color. 3. Create a little interesting wall with paint or simple wallpaper. You can keep it white and give it some patterned finish with smokey grey (you see how marble wall looks something similar)..... And you can do without the curtain as well. Pic 4: 1. You can make this into a gallery wall and put photo frames along with paintings from high up to mid of the wall. mix and match and see what works here. When hanging colored photos keep some border while framing that looks better. 2. The single chair is occupying too much space. Instead you can replace it with a Blue/White Ottoman (cheaper option) or sleek wing chair (without arm rest) (a little expensive option). Actually you can buy two Ottoman and put the spare one on the wall end of TV unit and can alternatively use it as coffee table.

you can check with gray and glass cabinets with a recessed light on it. It gives the dazzling look to the workstation. Try to keep the upper cabinets have glass doors. and keep it plain grey wooden or ply in the downwards. install the recessed lighting in an uniform sections below the upper cabinet section to make it bright. Try to put up a pelmets and valances styled dark colured curtain if there is any window. as its a grey and white finish so try to choose the curtain that is quite matching maybe a light grey can go better ....

Hi Tanmayi, Going for white walls is always safe, this will helps in giving a light feel to the room plus gives a lot of scope to bring in the patters and colours to the room in other forms (like curtains, cushions, wall art/frames, etc) PAINT SHADE(2 Options) Would also like to advice you to have a subtle wallpaper either in the niche portion of the TV wall or for the entire headboard wall. (Assuming the other walls may have windows or doors) SOME WALLPAPER REFERENCE IMAGES: Later you can gradually bring in other elements as per your taste and time and pull up the room together. Hope this helps! Best Regards, CUBS Team!
