Dublin's somewhat famous for it's Georgian townhouses, and their multi-coloured doors. There are a few different stories as to why the doors have been painted in all the colours in the rainbow ...
My dad would have you believe the people of Dublin were told to paint their doors all the same colour in preparation for a royal visit. In a show of defiance, all the colours of the rainbow were used instead.
Another story I've heard is that the colour of the doors, and the surrounds helped drunk home-owners find their way home after a hard night on the sauce ... before houses had numbers. ;) So instead of remembering that your house was number 14, you'd remember that you're looking for a bright red door with a triangular top. ;)

This was entered into a competition for work. It didn't win, but it did get into the top 12. ;)
