History of TVR purple?

[Tus 373]

Does anyone know much about TVR's use of the 'Pantone Violet' as their corporate colour? I would be interested to learn (for historical research) why purple was chosen and how long it has been in use for? It certainly makes a bold statement, and a high percentage of cars rolling out of Blackpool have been painted purple. You would not see that with many other marques.

Cheers
