Have you ever painted a wall thinking it was going to be white and when light hit it in the morning it looked more yellow? Depending on which way your room faces light will always change the colour appearance of the paint on your walls.
Think of colour as having a temperature, you can easily section colours into cool and warm, blues and greens being cooler, yellows and reds being warmer. Even black and white can be labelled like this, black being warmer and true white being cooler.
North facing rooms
If you have a north facing room you can use either cooler or warmer colours as this light wont tend to change the appearance of the colour. You will get a limited amount of cooler light later in the day, therefore most colours will work well.
South facing rooms
The same can be said if you have a southerly facing room as you will get lots of warm light. When you have lots of warm light cool and warm colours can work well. Like the north facing room the colours wont change that much during the day. So this is the easiest light to work with. However light coming into this room will be very bright, so it’s easy to go too bright and create too much energy. Choose muted tones to help balance this.
East facing rooms
Eastern facing will mean you will get light in the morning, it’s a cooler light and as the day goes on it can appear more bluish. Here it’s best to use cooler colours like greens and blues and cool whites. Also the light in the morning will make your colours appear brighter so in a bedroom don’t go too white, soften with a light blue feature wall.
West facing rooms
These rooms have light in the afternoon. They have both cool and warm light so again you can choose from either group. Grey works very well in this room as it looks cooler in the mornings and then warmer in the afternoons. Hopefully this will help when making decisions about colour. Always test and get samples up on the wall and live with them for a few days, observing how they change in the light. And don’t forget if you go for a strong colour, it becomes even stronger the more walls you paint it on.
