The way colour behaves is greatly influenced by light, so when choosing a colour for your room you should consider both natural and artificial light sources.
The appearance of your chosen colour will vary depending on the level and type of natural light in a room, as well as the time of the day and even the time of the year.
NORTH FACING ROOMS
Light from the north is generally cooler and less forgiving. Rather than trying to fight this, try using dark, strong colours to create a feeling of luxury and intimacy.
SOUTH FACING ROOMS
The easiest to decorate, rooms that are subject to southern light are filled with warm light most of the day.
