“We have just screened Il deserto Rosso, would you please let us know if Technicolor desaturated the film. Also we would like any information that you can get regarding types of filters used, etc. One of the credits on this picture reads: 'I colori ‘TINTAL’ sono stati forniti dal COLORIFICIO ITALIANO MAX MEYER' I think the translation of this credit is: 'The colors ‘TINTAL’ were provided by MAX MEYER ITALIAN COLOR INDUSTRY' What exactly is 'TINTAL'? Did the MAX MEYER Company supply the prints for the sets or did they work in conjunction with Mr. Antonioni and Mr. di Palma to design the colors of the sets, or what?"
--Letter from Alfred Hitchcock's assistant, Peggy Robertson, to Giulio Ascarelli of Universal Films in Rome, April 1965, as quoted in "Notes on Some Limits of Technicolor: The Antonioni Case". The "we" refers to herself and Hitchcock.
