You have to look pretty hard to find color in the typical Parisian building but whenever I do, I feel like I've won the lottery. Mosaics, ceramics, brickwork: I love them all. These details are hard to photograph from street level so my apologies for the wonky angles. So just consider these pictures documentation, not works of art. If you're heading out for your own treasure hunt, stick to the arrondissements with numbers in the double digits where 19th century architects and designers let their imaginations run wild.
