A study which quizzed 2,000 people about all aspects of their lives has revealed those who live in homes with a red front door are the happiest.
Over half of those polled were convinced the front door colour gives a lot away about its owner and the type of person they are.
And as such researchers found red front door owners are the biggest extroverts and are more relaxed in their approach to life.
Those with scarlet coloured doors are also the happiest generally, with white, green and brown all colours of the people who were most content in life.
The study also revealed that black front door owners are the most successful in their careers, while those with purple doors are the most sociable and the most likely to have a group of very close friends.
And a pink front door is the choice for those who are daring, and who also have the most friends.
While going for the orange or terracotta look might not do much for your working life, it was the colour chosen by people who were happiest in their relationship.
People living behind a green door are the most trustworthy, while pinks are full of mischief.
A spokesman for Farrow & Ball, which commissioned the research to launch their Great Outdoors competition to find the world’s best exterior door, said: "A front door is the first thing you see when you are approaching someone’s house and can tell you a lot about the home and its owner.
"It shows that colour can say so much about our personality and the front door can be seen as an indication of the type of person we are.
"The research indicates that Brits are perhaps subconsciously painting their front doors to reflect a particular mood or personality."
