Origin of Katie Scarlett O'Hara's middle name
Those were great symbolic meanings which you gave, Genis, and perhaps the author had some -- or all -- of those in mind when she named her character.
In the novel, the origin of the character's middle name is given as having been a family surname in Ireland. And the surname Scarlett, though associated with the color, is more specifically an occupational name for a dyer or seller of bright fabrics. (*A Dictionary of Surnames* by Hanks & Hodges)
Just a bit of Gone with the Wind trivia... Author Margaret Mitchell orignally planned to name her character "Pansy O'Hara". Fortunately, her editor didn't like that name and asked her to change it.
