Is there a correlation between colorful cities and happy residents? Apparently Bristol is ahead of other English cities on the happiness index and here it is below with colorful building facades.
Or maybe it's a cycle where happy people paint their buildings in bright colors and that makes other people happy? In the case of San Francisco (below), all it takes is one quirky neighbor to get half the block on a roll.
I hope architects and developers know that color can make otherwise boring multi-storey buildings a lot more interesting! For more photos of colorful cities, go to this Buzzfeed post.
