Just a random comment...
I think and I may be wrong as I am going back years ago - when she first came out with that pixie cut, she was also advertising a particular cosmetic brand, L’Oreal? The pixie cut emphasized her made up features perfectly and her face, in that pixie cut was on advertising merchandise everywhere, entrenching the “Halle Berry” look, a real coup for the brand.
In an interview with Oprah at the time, she was asked what was the colour of her hair - it was a really lovely colour. And she said, she actually didn’t know. She said her stylists actually chooses the colour and they create the look for her, such as that “Halle Berry” look and she goes with it.
...In the pics above, she looks nothing less than smoking..the long hair looks lovely.
