William H. Gass said this quote

“ Still, we permit the appearance of our meats, sauces, fruits, and vdgetables to dominate our tongues until it is difficult to divide a twist of lemon or squeeze of lime from the colors of their rinds or separate yellow from its yolk or chocolate from the quenchless brown which seems to be the root, shoot, stalk, and bloom of it. Yet I hardly think the eggplant's taste is as purple as its skin. In fact, there are few flavors at the violet end, odors either, for the acrid smell of blue smoke is deceiving, as is the tooth of the plum, though there may be just a hint of blue in the higher sauces. Perceptions are always profound, associations deceiving. No watermelon tastes red. Apropos: while waiting for a bus once, I saw open down the arm of a midfat, midlife, freckled woman, suitcase tugging at her hand like a small boy needing to pee, a deep blue crack as wide as any in a Roquefort. Split like paper tearing. She said nothing. Stood. Blue bubbled up in the opening like tar. One thing is certain: a cool flute blue tastes like deep well water drunk from a cup. ”
