I guess no Grimm before felt the need to ask XD  Or no Wesen lived long enough to tell (if they'd bothered to ask). Even Nicky didn't care until that wedding thing.

But how do you hide the change of colour? Nicky lives in Portland, not Miami. It's not exactly a place where you can wear sunglasses all day long and not be recognized.

Oh, and yes, they said it goes completely black, no difference between pupil, iris and all. Like this http://www.fashion-contactlenses.com/contact-lenses/Black-Sclera-Lenses.html
