The blue colour of this blind seemed to me, not perhaps by its beauty but by its intense vivacity, to efface so completely all the colours that had passed before my eyes from the day of my birth up to the moment in which I had gulped down the last of my drink and it had begun to take effect, that when compared with this blue they were as drab, as void as must be retrospectively the darkness in which he has lived to a man born blind whom a subsequent operation has at length enabled to see and to distinguish colours.
