Hi. If you plan on keeping your bedding as it is, then I suggest you pick up a very light lavender from it for the ceiling -- something like the colour below.

The Area of my Living Room is 19ft X 13ft and i want to have a false ceiling , but confused on what should be the design as i have also need to make sure that i have to manage the ceiling lights through out the living room and also have to place the fans

Cool shades - greys, blues - would offset the dark, warm tones nicely, but you might use any light to midtone colours you like as accent here. May I suggest you paint the walls in an accent shade, so that your bed stands out more? It is also nice when the accent rug allows you walk in bare feet around the bed, which would mean a minimum 2' border beyond the bedframe sides, ( much more than that, and you will hit the wall, anyway), and a generous amount showing at the end of the bed.

I have purchased an indigo color 3 seater sofa. See attached pic. I am confused whether i should pair it with a yellow color wing back chair or a printed wing back chair. My living room dinining area is highlighted with a yellow wall. Rest of the furniture in my room is dark tan
