Pardon the progress in the picture here, but I wanted to report that black was definitely the way to go with the door (sorry you were outvoted, Mr. Anonymous Feng Shui and LiLu).
Dan put one coat on yesterday — and between the two of us, we'll put on two more coats. The black door goes well with the shutters, wrought iron and the brick work. And of course my goofy iPhone photo sucks compared to the view from the street.
Thanks for your help on this, guys.
