But do we know that Karen Holness will portray GOOD Witch of the North? In the books there is also the Wicked Witch of the North named Mombi so as far as we know she can portray her instead. Or maybe OUaT writers will combine those two characters in one...like she is introduced as a good witch and helps Dorothy but only for Dorothy to bring her something from Glinda or Zelena.

As for Zelena not being green, maybe she just like her sister had a chance to redeem herself so she succeeded with the help of Glinda and thus got her normal skin color back. But something happened (probably Dorothy is involved) so she turned green and wicked again and resumed here vendetta against Regina.
