Keep things cool Cooler shades such as grey and blue help walls recede, making the room feel more spacious and light. Bring home the sunshine Light but warm colours such as terracotta or yellow can mimic sunshine and make a space feel bright and airy. Pale ceilings Keep the ceilings in a light colour to make the room appear larger and lighter. While white is your safest bet, you can opt for mint or sage green for a pop of colour.

Hey, Yes, Sonnet L146 is very commonly used color home interior walls and a combination of white on the ceiling. You may also tryout some different color options for rooms as single color for the whole will be a bit bland.
