I used to frequently go to a particular development in Murcia in Spain. When the properties were first built the buyers were told that the houses had to be painted white or yellow.
As always someone painted their house a different colour - a fine purple/red which stood out quite nicely. Invariably one of his neighbours denounced him (anonomously) to the local council , along the lines of 'You can't do that and I'm not having it'.
In due course three officials turned up, (one to read, one to write, and one to supervise the two intellectuals). They produced a fine set of forms, asked many questions and finally produced a sheet with many financial penalties identified.
They smiled at him, which seemed to make him more nervous. They looked at each other and tore up the penalties sheet
"Your house is a fine traditional Murcian red. It is good to see traditional colours being used. There will be no further action. We will go and inform the neighbour who denounced you and is standing on his doorstep over there""
