Yesterday I caught the tail end of an interview with Amy Greene, the Appalachian author of an intriguing debut novel called "Bloodroot." A colour called "haint blue" (not sure if I'm spelling "haint" correctly) seems to be central to the story. She says that many windowsills and doorframes on backroads homes are still painted this colour, which is supposed to ward off "haints" or bad spirits.

So... can anyone give me a sense of how I might recognize this colour of blue? Does it match the colour of a particular flower? Is it the colour at the center of a clear sky? Closer to cobalt or teal?
