Barns aren’t the only things with an interesting color on farms, wither. There are also porch ceilings, for instance, which are often blue. In the south of the U.S., a sort of blue-green called “haint blue” was chosen to keep “haints,” or ghosts, away. And in Victorian times, people used blue to paint the ceiling of their porches because this looked like the sky on a nice day — making the porch welcoming on rainy days as well.
