A couple more items to throw into the mix.
Firstly, below is a page from the Spartan Guide for 1970-1980. Scarlet O'Hara appears in the 1973-76 list.

It was on the 1973 Marina colour chart so it would have been introduced in 73. I assume it was used on the Mini at the same time.
That would be very possible, the most books I have found so far don't mention models for paint codes only the year so it could have been on any Morris of the day. I have found it pretty hard to cull the list to exactly which ones were used on mini's and which ones weren't especially in the early years.
Later Leyland Australia paint colour cards had the vehicle application on the back of the colour chit. The set pictured below doesn't have any date information, unfortunately. Scarlet O'Hara is not listed.
