A Russian-American novelist and short story writer who experienced *synaesthesias of the grapheme-colour type, meaning that he perceived coloured textures and shapes in association with letters of the alphabet. Nabokov referred to his own condition as colour hearing, although he was well aware that sounds were not involved in the experience. As he wrote in his autobiography, “Perhaps ‘hearing’ is not quite accurate, since the color sensation seems to be produced by the very act of my orally forming a given letter while I imagine its outline. The long a of the English alphabet (and it is this alphabet I have in mind farther on unless otherwise stated) has for me the tint of weathered wood, but a French a evokes polished ebony. This black group also includes hard g (vulcanized rubber) and r (a sooty rag bag being ripped).
