I've been really curious about this door. It's located a few blocks away from our old apartment in the Marais, and every time we walk past it, the same questions come to mind: 1. What's with the square window panes in different colors? And why are some of them the same? 2. Is the color palette carefully planned or the result of years of haphazard broken window repair? 3. Did they seriously coordinate the colors of the windows to the natural colors of the exposed stone of the building? 4. Who painted the electrical box and facade of the adjacent building, and did they coordinate as well? 5. Is this all staged for everyone's amusement? 6. Am I missing the secret code? 7. Am I nuts? To add to the mystery, this door is located in the tangle of streets near Rue de Temple - ground zero for the Knights Templar circa 1300. Hmmm.
