One thing to note, basically all of them have changed color (Snow White actually looks a bit *less* pale oddly enough)* because the artist is really liberal with highlights and extremely bright lighting. It's clear they're trying to make them a bit more uniform and almost a part of the same art style, but they should have noticed how pale they kept making all of them, particularly those three.
