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 love dark shades but from my experience oil stains on a dark shaded cabinets in kitchen specifically are more prominent.

Not necessary to use only paint for the change. There are different applications like wall papers, textured particle board, wooden panels etc. It actually depends on who is using the room. For the changed looks, go for wall paper on one wall and color selection as per the age of the user.

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