well my first response about the mordians was to dan who had taken it upon himself to insult the mordians and the 2 squads i have within my army right now painted as US Marines.
the color blue can mean so many things to so many different cultures. on tallaran i believe that water is very important and in real war grenades are a god send. so hey lets throw this explosive at the enemy and watch the destruction.
also the color of metals/plastics can differ from planet to planet. maybe the resources the tallarans use to make their grenades come out blue.
or maybe its just to get you to notice the grenades.
