Haint Life Grand?

There is an old, Southern tradition, especially popular in Gullah areas, of painting windows and doorways a bright but light blue known as "Haint Blue". It was thought to prevent evil spirits from entering the house.

This is a brighter, darker color than the sky-blue shade used on the ceilings of porches. That tradition was borne out of a belief that the color would deter flies, who would not land on it, believing it to be the actual sky.
