Hair changing

In the games, Terra’s hair is green while in the fmv it is blond. If a new remake of ffVI was done (a completely new remake like ff origins and DoS) her hair should remain green? or should it be blond? I’d make it blond, she looks better.
And the same thing from bartz, His hair is made white but the game character’s is brown, for me, THIS character should remain as he is in the game, the white color of hair makes him like a real travesty.

How bout you??
