That's very interesting. Many of the color differences are VERY similar to The Little Mermaid's recoloring(?).
I don't know if they are messing with the colors so they look better on uncalibrated televisions or that we are seeing corrections to aging and older transfer methods.
I'm surprsied no one at Disney has stepped up to explain considering some of the flack they've taken. But then again, they don't bother to defend the 'Home Theater' audio mixes either.
