Considering when the original poems were written which were used to build this film upon; it was in the Nineteen-seventies. In the United States we were still healing from segregation/Jim Crow. "Colored girl" was a term used for little black girls and grown black women, which is why that's what you saw in the film. It is also why it's called what it is. It probably was not misleading for the majority. I'm sorry it was for you. It must be put into context. This is a cultural thing that was not meant to address people all over the world. This was originally meant to address black women in America.
