During the course of the 2011 Project, I am including a series of pieces each dedicated to a specific color. The color for today is blue. In particular that sky blue, so candy sweet and practically artificial it is usually only found in postcards. Postcard Blue? Is that that the name of a color? And I am always finding uses for old postcards, so feel free to send me one from your summer vacation. It may even turn up in a piece of art later this year.
