Gallery walls are popular. You can do a nice geometric stencil in a metallic. But I'd prefer wallpaper. You can match your paint color to the background so it looks like a stencil, but it's faster and you'll have fewer imperfections. Many patterns come in temporary papers made for renters if you are worried about the removal process.

HRD , Love song is good as well. TBF the shades starting with L are so close that it's difficult to identify one from another :) Thanks, Nitin Cornerstone Designs, Bangalore

When the sunlight doesn't touch the wall surface, white tends to look grey and dull. Window Walls tend to have this problem especially if none of the adjacent walls have windows. One trick to liven up the window wall is to paint it in a rich, warm yellow tone. As shown in the attached picture. But don't paint any other wall in the room in this colour, as it will be overwhelming.
