1878 Art Jrnl. Apr. 109/1 We have been forcibly struck with the last new process for the pictorial reproduction of works of Art and of Art manufacture, ‘Photochromy’, a process by which a photographic foundation is utilised for printing in colours. It is the invention of M. Léon Vidal.

1891 Sandusky (Ohio) Daily Register 23 Apr. The color in the red seals and the green banks was once a protection, but late discoveries in photochromy makes [sic] it easy to reproduce the right shades.

1900 Science 21 Sept. 445/2 Partially successful experiments in photochromy, or the direct reproduction of color by photography, were made over a quarter of a century before the announcement of Daguerre's discovery.

1950 Science 10 Nov. 554/1 The same factor that appears again and again in the history of photochromy: namely, the favorable influence on color production of a previous exposure to diffuse light.

2. The art or process of colouring photographs. rare.Apparently only attested in dictionaries or glossaries.
