According to Jedi vs. Sith: The Complete Guide to the Force, the color of the lightsaber merely reflects the type of crystal used to create the blade.

There are no hard and fast rules in the movies. Often they are production choices. The one Luke made for himself was supposed to be blue but green worked better on film while Windu's had to be a different color to set him apart during the large fight scenes and they settled on Purple because it was Sam Jackson's favorite color.

Try again.
