Laser colors:
Apparently the color (wavelength of the visible part) has nothing to do with strength of the weapon, but it's only used as an ID method.
Rebels use red lasers and Imperials use green ones in all sizes and weapon mounts, from a fighter or mechanized troop small cannon to the Death Star main weapon.
The question is: is it worth it to make different Versions of the same weapon that only fire in different colors?
