I've seen beautiful heads of hair in all shades. Some of the most striking are beautiful copper reds, thick black hair, and this shiny shade of blonde I've only seen once in real life. I remember reading in GoT how a character's hair shone like spun gold. And it's true. There was a young woman I had biology with and her hair was so shiny and beautiful.
That being said, I don't think one is better than the other, rather my obsessions are more like intense fads.
