Blue painted porch ceilings can be found in most locations throughout the United States in one form or another. On the East Coast, it is not uncommon to find Victorian Mansions implementing a variety of blues, greens, mustard yellows, and terra cottas. The Victorians loved to paint their homes in colors that reminded them of nature, and a blue porch ceiling was obviously a nod to the sky on a beautiful clear day.
There is also a belief that a blue porch, and blue window trimmings also serves as a deterrent against insects, who are fooled by the color into thinking it is just a continuation of the sky, and thus, don't "settle down." While this is a very romantic notion, the truth is in the chemistry: The formula for these wonderful blue paint shades was often a milk based paint using lye as an ingredient. Lye, being a natural insect repellent, was actually what was causing the bugs to keep their distance.

Today, there is a huge design aesthetic devoted to paying homage to Haint Blue, but many people still choose this as an outdoor color scheme based on a strong family tradition. I personally love it and find it fascinating and whenever I explore an old building, I always make it a point to note any usage of "haint blue!"
