Hi Vijay, This looks like 7624 Dry Sage. Better to get a swatch test done on the concerned wall before you finalize. Good luck!

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.
