Or this one:
I would do it. Especially if the house provided a darker background. From what I found on my friendly Google search a green door symbolizes nature, growth, safety and it attracts wealth if you adhere to Feng Shui practices...worth a try, huh? Ok maybe lime is too much. How about...
The ubiquitous red? This is the color in Feng Sui that says "welcome". In early America it represented a place to rest and stay the night. In biblical times, Hebrew slaves used a red door (now, they used lambs blood but I don't think we need to go that far....) to encourage the "Angel of Vengeance" to pass by. Red doors on churches represented the blood sacrifice and that the area beyond was sacred.
In Scotland doors were painted red to signify that the mortgage was paid off!
(those crazy Scots!)
Grey. The "In-ist" color going right now.
Have I convinced you yet?? Opps-are you off to the paint store?
What color is your door???
