The colour of his skin is due to the fact he was de-aged in the movie. If you look up close, you can even notice some extra bit of smoothness around his face (in some lighting conditions), which looked even weirder than the colour in my opnion. The film's really good though.

This is the movie equivalent to Radiant Silvergun and Ikaruga.
