"The Twin Ion Engine (TIE) fighter was originally designed to be blue, but the blue screen technology of the time couldn't cope with a blue ship, so it was painted grey. As the technology improved through Episodes V and VI, the TIE fighters got a bit bluer."
Ooooh! So it was George Lucas's original intent that the TIE Fighters be blueish, and Adywan is just restoring that intent!
