Is there a history/meaning to a red front door?
We see that a lot of old (and new) houses at least currently have red front doors, even if there is no other red trim on the house.
Other than it's supposedly a good thing according to the rules of Feng Shui, is there any other symbolism or history to red front doors?
When did they become popular?
Are they appropriate for a house built in the 1840's? If so, what colors would be appropriate for the rest of the house, other than all white which we're not considering as an option?
