“In A Descriptive Handbook of Modern Water Colours, by J. Scott Taylor…. London: Winsor and Newton, 1887, neutral tint is described as ‘A compound shadow colour of a cool neutral character. It is not very permanent, as the gray is apt to become grey by exposure’. Has anyone besides this author ever made a distinction of meaning between gray and grey? I do not know how the distinction is to be converted in speaking unless the words are differently pronounced” (1897).
Glad to know that the gray / grey split in English has been confusing people for well over 115 years. What’s going on in pigment company Winsor & Newton’s world where gray turns into grey eventually? An interesting read about the etymology of the mysterious color and it’s uncertain linguistic origins.
