In Buenos Aires there is a location or neighbourhood called " La Boca" where houses are painted with strong saturated colours, red, blue, green and so on, it looks very strange and unusual.
Why? The story:
La Boca is located in the port and harbours and poor people and port workers lived there. Ships need painting and so ships were painted and always remain some paint cans and so, sailors brought half can or even a full cam of paint as present to some lady or not so lady living in the poor's houses and houses need to be painted.
Ships are painted in one colour and so houses were painted with this colour, when there was no more available paint cans from the ship the painting of houses stopped and remained some houses painted or half painted and other houses not painted.
With the next ship in the harbour the available colour was other, so within many years La Boca turned into a rainbow.
This is one or more century old story, today many parts still remains as a traditional place and for tourists, but nobody paints in that way!!!

Stupidity also evolves!
