A picture is worth 1,000 words of advice at Houzz. Please comment here and use the Attach Images button to add pix of the space where you have the dilemma. Do you have an inspiration picture, piece of art, rug or fabric that is determining the color for each bedroom or are you just grabbing these colors out of a hat? White goes with all of them.

For each bathroom choose a neutral color that U see in the tile Here is how to find the perfect wall paint "match" http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/

The dark blue and white combination at no.1 looks like a perfect combination of colors, furniture, furnishings and accessories to give it a complete and cozy look.

I would say at present your room is too crowded. also too bright /shiny colors. In India large / wall to wall rug/carpet can be problem with dust so a small cotton rug/carpet/dhurrie would help you. Also as Celerygirl mentioned please remove those sofa covers. add few cushions with nice cotton covers (ikat/block printed covers are quite cheap and easily available online) Get simple cotton/ or mixed curtains. Some wall art/framed posters /photos would be nice on walls. Also sheet on the diwan should match the color of your sofa.
