Was curious how the color shift in AotC would come found, found this scene recomp and sequence shift: (need to check the DVD, maybe this was done for that, and just didn't make the HD)

This shot Anakin and Obi have been shifted frame left.
Same lightning just shifted over.
Then the establishing shot of the power couplings has been moved from the middle of the sequence to the end.
