Where does Anne show uniqueness with her red hair and her unique personality.

From the text:

Nobody could who has red hair. I don’t mind the other things so much—the freckles and the green eyes and my skinniness. I can imagine them away. I can imagine that I have a beautiful rose-leaf complexion and lovely starry violet eyes. But I cannot imagine that red hair away. I do my best. I think to myself, ‘Now my hair is a glorious black, black as the raven’s wing.’ But all the time I know it is just plain red and it breaks my heart. It will be my lifelong sorrow. I read of a girl once in a novel who had a lifelong sorrow but it wasn’t red hair. Her hair was pure gold rippling back from her alabaster brow. What is an alabaster brow? I never could find out. Can you tell me?”

Red hair is also said to be accompanied by a fiery temper.

“How dare you say such things about me?” she repeated vehemently. “How would you like to have such things said about you? How would you like to be told that you are fat and clumsy and probably hadn’t a spark of imagination in you? I don’t care if I do hurt your feelings by saying so! I hope I hurt them. You have hurt mine worse than they were ever hurt before even by Mrs. Thomas’ intoxicated husband. And I’ll never forgive you for it, never, never!”

Stamp! Stamp!

“Did anybody ever see such a temper!” exclaimed the horrified Mrs. Rachel.
