I was last in London about 6 years ago and only for a couple of months, so I have time to explore beyond the most famous sites and landmarks. This time, I made sure I had plenty of time to stroll and discover, and I was astonished by how colorful London is. Much more so than Baku. Perhaps it's because the climate is colder and grayer, and people need the color to lift their mood. Here are some of my favorite streets, doorways, and windows.
