Colour makes a space look messier or pleasing. Narrower spaces can use lot of white and a tinge of blue walls to make them look appealing. Be it bedroom, living room, and bathroom, if you have a very small living space, then use a single tone of white walls throughout the house. You can use blue for panels, ceiling, cabinets, and furniture. Use a lighter shade of blue in most of the rooms and a darker shade in the bathroom.
Create magnificence with white
Use a teal or beige circular lamp for the ceiling. To balance the pristine white of the walls, use light curtains in lavender and teal shade. You can also use kitchen bowls and mugs in a single solid colour. Avoid red, orange or any bright colour in pillows, bed sheets, curtains, etc.
Using blue for a single side wall in ink blue or sky blue shade can be very pleasing to the eye, even if it is a small space. Use compact lamps and frames on either side of any open panels of your wall. Keep a single couch with an interesting fur toping cover and a cushion. Avoid wall papers, decals, and any other large pictures on the wall.
