Most unnatural hair color that you have seen in anime

[Blackangel]

i think it's dark blue. i never expected a very rich girl to have it and that's not a died hair going by her family. what is the most unnatural hair color that you have seen?

 

[Rinko]

Two different hair colours usually.
Like Hela in The God of pain's groom and I don't remember any other anime and manga as of now

 

[Heatman]

I believe that most of them carry unnatural hair colors as far as it's not black or golden. All the red, yellow, blue, pink, orange, etc are not natural hair colors.

I haven't found any such unnatural hair color yet. As most of them are either black or blonde. But in dragonballz, Goku had some unnatural set of hair, pure yellow and resembles banana like shape. :laugh:
