Starting with the bedroom suites...have your bedding selected. Choose a color that coordinates. You can accent the headboard walls with a darker color and carry that darker color into bathroom on the walls, or continue bedroom color and carry the accent color into your towels and shower curtain. I would paint kitchen and 2 dining room walls the same color, selecting a darker color for the drama in the dining room and contrast with your kitchen cupboards (such as your green color). The other walls in your living room, foyer and hallway, should be your neutral color such as a camel or warm gray. This neutral is bumping up against all of your other room colors. So, it will make a good transition from room to room. On the bold side, you could find a great wallpaper for the two walls in the dining room. Don't forget to play up your foyer with furniture for that first look impact. Selecting your bedding first, allows you to tweak your paint color and hue, and the darkness of your color. Enjoy.

A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

Your choices don't flow well to me. The flooring in your photo is pretty (very dark...are you okay with it showing every footprint, smudge, and dust bunny? If so, that's fine). From all of your options there I would do white cabinets with the Himalaya White granite. But you said ignore the granite. :) I would go for the gray cabinets with white quartz everywhere in that case, but personally I'd worry about gray cabinets being very dated in a few years. Is there another quartz option that you could pair with the white cabinets that is light in color and maybe has some movement, like LG Bianco Drift?

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.
