Meriden built Triumphs never had paint "codes". All the colors had Triumph-created names. There is a tech thread on paints / colors and where to get them, I'll link back.
"Aubergine" is the correct color, with "Alaskan White". My bike is correct and the photo I posted is in decent light where you get a good rendiion of what it looks like in person.
The colors must be laid over a base coat of Gold Sheen (very fine metallic).
The paint was sourced from Don Hutchinson who is the American authority on the correct paints for old Triumphs.

I will get you the European source.
