If you are traveling to the coastal areas of Georgia, South Carolina, and Florida, you may notice how many of the houses have blue porches or at least blue ceilings on their porches.
This is a Southern tradition based on the Gullah culture of early enslaved people in the United States. This tradition uses haint blue on the porch and ceilings to ward off evil and wandering spirits from entering the house.
The word haint is a combination of the words haunt and paint. There is a belief haints lost souls or restless spirits. The blue paint represents water, and many believe the spirits cannot crossover water.
There are two other reasons people paint their porch a haint blue; the first is to repel insects. Insects believe the blue paint on the ceiling is an extension of the sky, and they move on by avoiding the house. At one time, paint was made out of milk, and this type of paint repels insects. The second reason is calmness. The beauty of the haint paint brings a calming influence over the people sitting on the porch. For whatever your reason is, to be calmer, repel insects or detour the dead spirits, haint paint seems like the winner.
