its not blue vs blue
okay i just have to sya that i am gettying sick and tired of people saying that the ep3 duel will be blue vs blue....
as defined in the star war svisual dictionary:
if two are battling, each saber must be a different color, or they will pass through one another.
you cant deflect a lightsaber if its the same color as yours..
they'll just go through eachother
their frequencies have to be different and the main (almost only)part of the frequency is the color
