We drove through these places called barrios in LA and they had houses painted like this. It was so cool. It felt so cheerful. In Italy they paint their skiffs and boats like this too. The harbours can be really colourful. I bet voices echo really well in those alleys. Be careful what you talk about, your neighbours will hear you.
I've seen the colorful docks and boats too (I actually have photos of them somewhere, floating around in my archives). Some of the posts actually have colorful (and sometimes creepy) faces painted on them.
