‘Black Door Lemon Wall' is a photo I took while wandering around the French Quarter in New Orleans. The warm colors of the buildings come from the creole heritage of the region. The term ‘creole' denotes people born in the region or descended from people born in the region rather than colonists born in their mother country or first generation immigrants. For New Orleans this includes a mix of French, Spanish, and ‘free people of color'. They all shared a common catholic tradition and much of the architecture of the French Quarter has echoes of French Mediterranean style (according to the font of truths, half-truths, and outright lies that is wikipedia).
