Here is an elegant paint color with an interesting historical backstory. Charleston green is a shade of green so dark that it seems black. Indeed, Wikipedia just straight-out lists it under black instead of green, so perhaps Charleston Green really is black. The story goes that, after the American Civil War, mass quantities of black paint were provided by the Federal government for reconstruction. The proud (albeit economically ruined) aesthetes of Charleston could not bear to paint their lovely vintage houses black–so they mixed in small quantities of yellow in order to create an exceedingly dark green.
Whether this story is true or not, the color is very dramatic and pretty, although admittedly subtle. In the modern post-post-Civil War period, Charleston Green seems to mostly be used for shutters, doors, and accents where it looks especially good against white, cream, bricks, or pale green. Maybe it is not necessarily so much a response to northern aggression as a solid aesthetic choice. I feel like I’ve seen a whole house or two painted this color in my own neighborhood in New York, and weren’t the carpetbaggers supposed to have come from here?
