That’s not a point William Gass makes. He doesn’t need to. But it’s something you can learn from reading him, from letting yourself drown in On Being Blue. For Gass has an ear like a Pantone chart, exquisitely alert to the semitones of sound and sense, fifty red words here and a hundred greenies over there. His blues themselves are enough to swallow you down, and if you weren’t going to read it in just a few minutes I would quote the entirety of this book’s page-long first sentence, with its rattletrap inventory of some few of the things that particular color can be, the “Blue pencils, blue noses, blue movies, laws, blue legs and stockings . . . beards, coats, collars, chips and cheese . . . watered twilight, sour sea.” Russian cats are blue, and oysters, the Social Register too, and it is also, he says, the color of “everything that’s empty,” which makes me remember the high windows that Philip Larkin opens onto “the deep blue air, that shows / Nothing, and is nowhere, and is endless.”
