What arguments can prove that "the Last Leaf" of O. Henry is a typical local color story?

The story takes place in New York City, in an artists'
enclave in Greenwich Village. Many local landmarks are mentioned, such as Delmonico's on
8th Street, 6th Avenue and Washington Square. It is well known that Greenwich Village,
during the time this story was written, was a haven for musicians and artists. Further,
the influence of Dutch architecture is referred to in the story, and the Dutch were the
early settlers of New York. The story takes place in November, and the weather is a
typical cold, rainy, New York City bone-chilling month. So, I would say that these
elements of the setting prove that there is local color in this story. The characters
that inhabit the story as well are artist-types, and that adds to the local
color.
