We have a summer home in rural Wisconsin, and all houses have red and white "fire codes" for the fire department to find the house, since most roads
don't have names. It's probably something along those lines, and Maine chose blue for visibility.
An example of the color difference between townships, even, as far as noticablitiy goes, can be seen in our fire hydrants. Every town chooses their
own color, and here in Chicago, we have yellow, red, lime green, and (oddly, since it snows here) white.
