What's the name of that hair style, or at least the designer who used it in his/her fashion show?...?

I don't remember where I found the link, but I read the article probably a little over a week or two ago. Basically it talked about these models who had their hair divided into two colors, split down the part in the middle of their heads. One side of their head would be covered in normal brown while the other would be totally red or pink, very clean and neatly done. Same with black hair, or blond/red. Is there a name for this hair style, or could anyone at least tell me the show/designer so I can find those pictures again!??! I've been googling "two-colored hair," "duo-tone hair," etc and I can't find it! Please help, thank you so much!! :)
