Hi Simran, I totally agree with you. The string lights are beautiful but do not last long. You can use lanterns instead, they look equally stunning. Try getting some in geometric shapes or paper lanterns. If you're still hooked up to the typical string lights, you may go ahead with battery powered LED string lights. A little pricey but worth every penny! Hope you enjoy lighting up the place :)Geometric Pendants Battery operated LED's Good Ol' Paper Lanterns

I have one textured blue wall and other 3 are very light gray. The lamp is to be set on a gray wall.

Hi, Consider this: Color of lights depends on the substantial area for which it is going to be used. For residential we normally go for same color light; especially warm light. An exception can be made for landscaping, even there it's limited. Different colored lights are used in clubs, pubs, concerts, majorly places that provide entertainment. Lights are not only for visibility purpose, choosing right color light provides visibility as well as calm to our eyes. Shapes as in; you can have LED lights as well as decorative lights. But I don't suggest different shapes of LED lights for the same room. Hope that clarifies your question. -Thanks, -Neelam -Lines and Profile

The living room window itself does not appear to be designed to let much light through. Please show a photo of that window, also of what lies outside the window. In the meantime, I suggest that you replace the builder-installed window with one of your own choosing. Use toughened glass rather than this heavy grill. Minimise the frame, if possible, particularly if there will not be much air coming through. If there is the potential of air but not much view, then have a sliding or bifold window that maximises the opening. On the blank wall outside, if that's your view, put up a green wall, creeper, something to improve the outlook. For nighttime viewing, add mild uplights in a natural white shade, focused on the greenery. Or else, you may be able to put up a reflective surface on the facing wall, to bounce in more of whatever light there is. Such as a coloured glass mural if not a plain mirror. Once you have maximised your window, move on to the wall to the right of your living room photo. That is, the wall that your living room shares with the west bedroom. Use a very large mirror on that wall to expand your living room visually and to bounce more light around. To cut down on expense/effort you can make it out of several standard-size sheets rather than one giant sheet. However, if that wall is to be covered with storage, make sure the front surface of the cabinetry is fairly light-coloured and reflective. Last, if not yet satisfied, consult a lighting expert for this room. That would be useful. These are fairly expensive solutions, all in all, but they should help.
