based on observations, as only the new ships GTVA like Raynor and the Chimera, this type of weapon used,
placing a queen Ice Beam Cannon in a GTD Hecate, (assuming that a reactor was a chaplain is able to feed)
the beam of light will remain thin, very cohesion, and accurate, but green, maintain the properties of cohesion and precision for designing the beam cannon, but maybe would lose rank and damage to be powered by a standard reactor, and not a new-generation reactor (Meson)
understanding that the color blue was chosen aesthetically, it will only look for a logical, to be applied, but also explained the weapons when they are, more lethal sound xD
Thanks for responding!
