Why did the artist choose to paint one octopus in blue and the other two without any color? Why were the first two in pink? Is there a reason, or is it just random? I am maybe trying to find a reason (statement?) for those tags, but in reality there might actually only be a person that likes to tag little, funny octopuses on the walls of Paris.
In the end all those questions will probably stay unanswered anyways… but I might stumble upon another octopus someday, on an other side of town and I can tell you this would make my day!
