Am I the only one who things your latest pics are too pink?

The adjustment to Mike's shot? Yes, went a bit too pink.

Another interesting nonsensical color shift on the blu-ray is the door on the Tantive before it's blown open. The walls become much more blue on the shot of the door where the explosion starts, compared to previous nearly identical shots. Presumably the shift was to get the explosion looking how they wanted.

You can imagine reasons for a lot of the color nonsense on the BD. Whenever there are laser blasts, they've got the saturation cranked up (probably to make the lasers look more impressive), and the skin tones look even worse as a result. It's also possible that they really wanted R2's blue color to 'pop', as shots with him present during the droid sale also are tweaked compared to surrounding shots.
