It doesn't even stay the same color in the hangar scene. The closeup of Shin with his hand on the plane and the next pulled back shot are from the EXACT SAME SCENE as the pic everybody else has been commenting on as being the correct color. It's not a momentary change in scene or darkly lit canyon shot... it's the same damn scene.
Any given still from that movie the blue looks different. In the canyon training scene when Roy drops down from above the blue is almost exactly like the toy.
While we're busy disliking everything about the saturation on the 0D in the other thread I'm curious why we're all okay with that extremely bright, pastel blue on this thing when the Perceval photo clearly shows a much darker blue all around.
