'Hain't' that porch ceiling blue?

Blue porch ceilings are a Southern tradition with spooky origins

If you are familiar with Southern neighborhoods, you have probably noticed one out of every four houses has a porch with a blue ceiling. The blue paint is not just any shade of blue – it is haint blue. 

The tradition or superstition of haint blue on the ceilings of porches, around windows and on doors began in the country of Angola, by the Gullah or Geechee people. Their descendants kept the tradition alive when they came to the United States, and as a result, it became a Southern tradition.
