The best colour combinations for interior walls are neutral in tone but have a strong, distinct accent colour.

Berger recommends using grey or white as the base and accent colours to bring out the room’s design. These colours will make your space more open and airy, which is especially important in small spaces.

Another option is to use two different shades of blue to create a sense of depth. This can be done by pairing one shade of blue with a darker shade of blue on the walls.
