Morocco and Tunisia are the places to go to photograph interesting doors. Many buildings go to a great deal of trouble to offer a decorative place by which to enter or leave. Often, they're past their prime but in some ways that only adds to the charm in terms of the beauty of decay. Blue doors and walls are especially common in both countries, which is strange, because neither of their flags have any blue. Knowing what I know now, if I was transported back in a time machine I would make sure I had the sole rights to sell blue paint in both these places. I'd be a billionaire now. Or maybe not. Some buildings look like they only get a coat of paint once every 50 years.
