If you can access your home, take some colour samples in shades you like with you and check the light and aspect of each room, that can change colours, some rooms may be a little dull and need bright or cheering colours others may be hot and need cooling colours. It is very important you consider this before you start. Then choose ideas and colours you like and that suit your room, and then go shopping to see what is on the market and available. It is no use getting your mind set on a colour for example and then finding you can't get a fabric in that shade. Flooring will most likely be common to all rooms so you have to ensure the flooring you choose will work with all your planned colour schemes in each room. Check out all your options and things will then start to come together for you. When shopping pick up as many swatches and samples as you can, even take photos of ideas if you are able, it will all help. Most important thing is to take it slowly. Don't try to have it all done at once. Aim to choose your floor coverings, then have all your rooms painted, and floor coverings laid before you move in. Furniture and furnishings can be added at any time afterwards.

There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

I'm not against colorful homes. There's bright, and then there's too bright. I wouldn't go with persimmon for the whole house. The photo you provided has lots of white trim which offsets the orange, but your house doesn't have that much trim (unless you were planning on adding some, which I think would look good no matter what color you ultimately choose, but even so, I wouldn't go with persimmon for the whole house, as it's still too bright). To repeat what @nwduck said, the other homes in the neighborhood don't appear to all be done in the bright colors, and so yours would stand out too too much. I like @deco's idea of the bright door, if you really love a bright color. For the rest of the house, any more subdued color would be fine, along with additional trim around the windows, and assuming that your siding color coordinates with your roofing color.

What a beautiful house, Shahbaaz! I live in a similar house - a 150-year-old colonial bungalow in Kumaon. You have already received lots of excellent advice from better-qualified people, so all I would say is, keep its age and heritage character the central theme. The white tiles do clash, I am afraid ... flooring with terracotta tiles would echo the roof and look lovely. The columns and the arches over the doors and windows are amazing. But I'd say, leave it all chuna-painted - there's a beauty and softness to it. Don't let the painters add too much neel (indigo) in the limewash -- in the hills where I live, they put far too much if I don't watch out and the result is a harsh white. Natural lime has a softer, creamy look.
