What happened to change Hurston’s perspective of herself and her color?

Hurston's perspective of herself and her color changes when she leaves home..... her safe space and moves into the outside world.

But changes came in the family when I was thirteen, and I was sent to school in Jacksonville. I left Eatonville, the town of the oleanders, a Zora. When I disembarked from the river-boat at Jacksonville, she was no more. It seemed that I had suffered a sea change. I was not Zora of Orange County any more, I was now a little colored girl. I found it out in certain ways. In my heart as well as in the mirror, I became a fast brown--warranted not to rub nor run.
