According to Incubus, "it's so much easier when seafoam green is in fashion". Not sure David McCandless can back up this statement, but he can tell you when this or any other color in the rainbow has been trendy. His new book, Visual Miscellaneum, aims to "explore a whole range of subjects as visually and beautifully as possible, with the minimum of text." The results include this color chart that organizes popularity of color by year. For someone like me, who gets a high just from flipping through a paint deck, this is fascinating!
