What’s your immediate reaction when you spot a front door painted in a surprisingly bright shade? If you’re anything like us, it’d probably make you smile, but it might also make you wonder about the people who live behind it – are they bright, happy-go-lucky types? Creatives? Would they be fun neighbours?

This gut-reaction isn’t so surprising when you look at the results of a fascinating new study into the psychology of colour and the exterior of our homes. Weathershield has revealed that Brits make an assumption about a person just 10 seconds after seeing the colour of their front door, proving that we are a nation that does judge a book by its cover.

Karen Haller, Applied Colour Psychologist agrees: 'The front door is traditionally the first impression the outside world gets, and gives an insight into your life. Taking pride in the exterior of your house not only improves the aesthetic of your home but can also add to the perceived value. A small change can make a big difference.'

So, which colour to pick? And more importantly, what message is it sending out?

People with pink front doors are thought of as the most out-going and mischievous, whereas people with lilac front doors are believed to be the most creative. Cream is most associated with a peaceful home, whilst people with yellow front doors are believed to be the happiest and most welcoming hosts. The research identified that Number 10 Downing Street is the most recognisable front door, with Brits claiming that the shiny black gloss makes the Prime Minister seem important and earnest.

And the other colours? See if your front door matches your personality:

Navy blue was associated with intelligence.

Black was believed to be the colour chosen by those who are the most mysterious.

Red was associated with passionate homeowners.

Grey was associated with sincerity.

So perhaps it's time for a repaint…

What does your door say about your house?
