Photos of the living room would be helpful.

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.

you shouldn't use any dark color nor too much of light color. According to me, ash gray color would compliment the room but again that depends upon your color selection of your clothes.

Dear Mr. Maverick, Hope you are doing great. Seeing at your post its very clear that you are a passionate person and taking your designing process seriously. Also you are accepting that you are not a designer yourself which is a good gesture against those clients who think themselves superior when it comes to design choices but knows nothing in real. I agree with above replies to share some information about your house starting with the floor plans as without these no one would be able to help you in any way. Also you need to understand that designing is a subjective and time consuming process and doesn't happen in an instant. If its just about getting ideas then you can find millions on google search. But being on Houzz platform is a great thing as its full of many talented professionals contributing to the solutions best way possible. I hereby offer my services and request you to go thru my profile and works and see if it interests you. I can show more interesting works if you insist.
