Hello Matteo,
I may be misunderstanding you but the paint codes you are requesting are:
71-75 Dune Beige code 416
76-84 Beige code 464
Roof and bezel:
71-76 Cygnus white code 012
76-80 white code 031
80-84 white code 033
Then I thought you may be requesting interior trim colours. If so I have to say that I have not found any trim colour references so, hopefully, it was paint codes you wanted.
Regards,
Rodger
