The legend of Haints Blue: In the south it was common to paint porch ceilings blue to protect the house from evil sprits. The Gullah people passed along this tradition. In the Gullah culture of the South , ceilings and sometimes doors and shutters were painted blue to symbolize water or sky. According to folklore evil spirits and haints, pronunced “haunts,” would be either be tricked by the sky or the blue symbolized water which they could not cross. Blue glass bottles were also hung in trees to trap haints.
In the past Haint Blue was mixed with milk paint formulas using lime and crushed indigo plant pigments. Today many people use pale or dusty hues but there is no standard color. The color ranges from light blues and blue greens to darker shades and gray blues.
