Hopefully, you'll be able to use the color crystals you get from dead Jedi or Sith if you desire to pick up their weapon as in one of the in-game videos.
Jedi Guardians have Blue Lightsabers, with the exception of The Exile who carried Cyan.
Jedi Consulars have Green Lightsabers.
Jedi Sentinels have [supposedly] Yellow Lightsabers.
Mace Windu was given a rare violet crystal as a reward or something I can't remember it's on his Wookiepedia page.
