[GAMEPLAY] Soraka turns blue instead of golden during Zhonya's stasis

as title says, when Soraka uses Zhonya's she turns blue instead of the normal gold. not sure why or if there are other champs who do as well.

tested this with a friend to see if it was just on my side, and he said he saw the blue, too.

here are some pictures. and no, not every champ for me turns blue, either.
