You're welcome! =) I think a shade of grey will be a great addition to the room. The red one in the photo doesn't really suit it. If you have any questions, feel free to ask! angelinavick@ymail.com

With white fixtures, keep your floors and all tile white or a stone that is mostly white. You can paint the walls above the wainscot (which might be glossy painted wood or beadboard, or you might employ a cabinet for the sink that was painted a very soft sky blue. One narrow trim piece of tile running through the white tile might be the same tone of sky blue. Then, add blue linens / towels / etc. [houzz=] Now, consider what other colors are in your home and select one that is clear and soft and lovely with white. You might use that color instead of sky blue. I used sky blue because it is the color of water and therefore always appropriate in the bath, but you can make the bath flow with the colors you have or plan to have in your home. If this was a master bathroom instead of a common or guest bath, I would shift the choices of stone and tile from white plus white to a lovely off-white, cream, or almond tone - like travertine. Use a neutral like chocolate on the cabinet and add color only with linens and perhaps some art on the wall. [houzz=]

Instead of the solid grey, you can go for sketches in grey with flashes of mustard/ yellow. Or, look up these links for wallpaper ideas https://goo.gl/images/OrCtY1 https://goo.gl/images/0ZpAmU

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.
