Welcoming the Red Zone.
We all know that a red front door adds instant curb appeal, but what does a red front door symbolize?
A lot, actually. It’s hard to pin down a specific origin of the red front door, but after a little research,ShelterPop.com traced the tradition back to Biblical times. As history goes, Hebrew slaves were instructed to paint their doors red to protect their first-born from the angel of death. Many churches also painted their doors red, with the belief that once you passed through it you were protected from evil. And in early American times, if a family had a red front door, travelers passing through by horse and buggy would know that a home was a safe place to stop and stay. According to the principles of Feng Shui, a red door symbolizes “welcome.” Perhaps more importantly than its historical meaning, though, is the fact that, according to the principles of Feng Shui, a red door is supposed to create a welcoming energy in your home. And the most exciting meaning: In Scotland, a red door means “mortgage-free,” since homeowners used to paint their front doors to announce to the world that they’d paid off their home.
