How do you know, when you think blue -- when you say blue -- that you are talking about the same blue as anyone else? You cannot get a grip on blue. Blue is the sky, the sea, a god's eye, a devil's tail, a birth, a strangulation, a virgin's cloak, a monkey's ass. It's a butterfly, a bird, a spicy joke, the saddest song, the brightest day. Blue is sly, slick, it slides into the room sideways, a slippery trickster. This is a story about the color blue, and like blue, there's nothing true about it. Blue is beauty, not truth. 'True blue' is a ruse, a rhyme; it's there, then it's not. Blue is a deeply sneaky color.
