My first question for you is do they have Ikea in India? They have the market cornered when it comes to smart and unique ways to furnish small spaces - and as far as I'm concerned, their specialty is clutter control! It would be helpful if you could post pictures so that we can understand your space a little better. I will say that, as far as paint color goes, the first color that comes to mind is white. It makes any space feel fresh and clean and spacious, and will make the smallest picture or cushion just that much more noticeable. In a small space this is good since you won't have room for a lot of these items!

Consider Grey or white. U could also use geometric or any pattern in mint green

Hi Idsshyam, For beige walls, white tiles/marble are a classic pair. This gives you a blank canvas to work. You can also go for darker wood tones such as mahogany or ebony flooring to contrast the lighter wall colour. A cool-tones beige would also complement maple, birch or walnut wooden floors. These can easily bring a contemporary look to your space. Hope this helps. Good luck with your home design.
