Same reason Mutsuki´s is green, Urie´s is purple, Saiko´s is blue and Shirazu´s yellow...

And the same one that makes Eto´s "green" as well...

Rc-cells.

It seems that becoming a one-eyed ghoul tend to do some quite "interesting" things with the pigments in the hair follicles...

That´s the only explanation I can think of.
