I always think a home is most beautiful when it blends in with its natural surroundings..choosing colors that Mother Nature has provided and adding additional colors through landscaping with living things in lush enclosed areas...tall plantings surrounding the flat walls could create lovely silhouettes that change with the light from day to night

You can do white entirely. The dark brown tiles will become the highlight. You could do dark brown only for the lines on your compound wall, or keep it white as well. Do Asian paints white without mixing any blue. Also white keeps the room temperature cooler.

colour combination plz

Always go for timeless colour combinations like beige, brown, grey, white or other muted earthy Color tones and shades. But make sure even you are making a combination of 2-3 colors they all have to be in ratio of 60:30:10 or 60:40. What materials do you use also matters a lot. Some people opt for aluminium composite panelling , some for stone or tile and some for even stainless steel. These all are the best choices but to make your home look modern and contemporary it has to be grey or beige no matter what you choose. And for more traditional homes go for stones, wall paints and even textured paint.
