IIRC the MKIX in Hitchcock’s Vertigo was Sherwood Green as was the very first E-type imported into Finland (#876420 3.8L LHD OTS Sherwood Green / Beige, Black hood).
jaguar “tan” for the early etypes is very orangey. it gets darker with age. when i removed the arm rests the vinyl door panel was very orange in color.
connolly “ochre” looks correct.
