Disruptors

Disruptors are just like phasers, except that when something gets shot with a disruptor the end result is messier and (if the target is organic) much more painful.
Disruption-based weapons tend to shoot secondary colors and phase-based weapons shoot mainly primary colors. I have no idea how this relates to the laws of physics in any way although it could be speculated that G.I.Joe and COBRA may be involved.
