CITY CODES
I've noticed, that every three years, whenever we have a new city mayor, the color and codes even the logotypes of all the minicipal institutions are changing.
I know this is not new, and that im not the first person to notice it; I expect some day that those who rule in the city hall included the political partys leaders, can fix a city law that can delimit this beheavior:

if they begin using the same colors (maybe they can choose one who doesnt represent any political party, or one who can represent all of them, -thats why the parties leaders must be there to choose-), we can have a more benevolous idea about the public institution, with the time, tha institution will generate our trust.

using the same logos, and color in the documents, transports, city services, the institutions will be solid at our eyes, progressive and fraternal.
