Why does Fatality change skin/hair color in the New 52?

Speaking directly about the series Green Lantern Corps:

Fatality starts off black, with black hair.

Then she is white with blonde hair.

Then she is black, with black hair.

I don't want to spoiler the series for anyone if you haven't read it, but for people who have...and knowing what I do know, I still don't understand why she would appear white with blonde hair? and then go back to being black with black hair? As if John wouldnt be able to tell?

Any help with this?
