I noticed in that clip that the rebel soldiers outfits change colors from time to time.

At 2:44 it looks like there is too much magenta in the image.

Then with the troops passing by when 3PO says, "They've shut down the main reactor, we'll be destroyed for sure!", they look normal again.

At 2:51, again they look too magenta

Now compare 3:08 and 3:09 - the part when the ship is being pulled in and the soldiers are looking around... Their outfits keep changing color!

PS: What source is the image at the top left of the clip?
