Satyanaran Nayek sir
Paint your north wall half Pink and rest of Smoke Colour and hang flower vase with pick roses on Pink wall and Grey colour flower on Grey wall. This is for material benefits. This is purely based on Shastriya Vastu. Instead painting wall you can stick colour wall paper. If not full wall from top to half wall but should cover two ends. Do not keep any waste material from North east up to end of Northern wall. Sample is shown below
