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.
