I’ve mentioned this before elsewhwere…on the VHS 1995 THX fullscreen release , there is a gaffe with the lasers on the TIE Fighters being blue instead of green in ESB. It happens right after the Star Destroyers take evasive action and goes into the asteroid canyon chase . It looks more like the laser fire from the Cylon raiders in the original Battlestar Galactica for a few moments , then reverts back to the normal green fire . I wonder what the story behind that was ? Any speculation or definitive answers out there ?
