Spurred by our Dublin Door post, reader and blogger, Leah, sent us this link, Color Obsession: Painted Houses, to colorful houses around the world. It's a great post and it really does again bring up the question as to what is it that makes one city more colorful than another. It doesn't seem to be climate as there are colorful cities in the north and the south, so it must be something else. And there is no doubt that San Francisco is MUCH more colorful than NYC. What could it be?
