Turbolasers - Red
Ion cannon - Blue
Proton/concussion - Black
The reason I think this, conjecture - haven't played the game, is the red dice just do damage. The blue have some debilitating effects so good for ion cannons. Do black dice ignore shields?
As to fighters using blue dice, it could just be that the 'ion' dice works best as most fighter weapons can't do much to capitol ships, and any additional effects such as canceling tokens is from maneuverability and being able to harass and distract larger ships/fighters.
