What is the real story behind the Dublin Doors?

Answer 1

George Moore lived next to Oliver St John Gogarty in Ely Place off Stephens white. Both were famous writers and both rather eccentric. All the doors of Ely Place were then painted white. Moore painted his door green so that the drunken Gogarty would not come knocking on it, thinking it to be his own door. Gogarty then painted his door red so that the drunken Moore would not come knocking on his door! So started the fashion."

There is also a story that the women were tired of their husbands going in the wrong doors when they were drunk, going up the wrong stairs, into the wrong bedroom and sleeping with the wrong woman so they painted the doors different colors to help them distinguish between them.

When Prince Albert, the husband of Queen Victoria, died, the Queen ordered all doors in the entire British Empire to be painted black. The Irish, being opposed to caving to such orders, immediately painted their doors as colorfully as was possible at the time.
