It would have a sorta blue tint to it. It wouldn't do really anything. For awesome results, I suggest bleaching your hair first. But bleaching it has life long consequences, like you probably will have a hard time regaining your natural hair color back.

I mean, if you want to turn it a nice light blue you'd have to bleach it and that would potentially damage it, other wise you can have a really dark blue that would barely show up, like the streak I had put in my hair.
