I just finished reading The Courtship of Princess Leia, and let me start out by saying that it was a wonderful book with exciting new characters and fitting conclusions to some returning characters.
Now, onto my question. In Truce at Bakura (it's been eight books since I read it, so forgive me if I'm wrong), Luke had his green lightsaber from Return of the Jedi. However, in The Courtship of Princess Leia, the book describes Luke's lightsaber as having a "blue glow" at least twice.
Keep in mind though, the text never actually says that Luke's lightsaber is blue; just that it has a blue glow. On the other hand, the author never states that his lightsaber is green either. Did I miss something? Did Luke build a new blue lightsaber inbetween Truce at Bakura and The Courtship of Princess Leia? Or is the author merely describing a color tint that Luke's green lightsaber gives off? Any help on this matter would be greatly appreciated. Thanks.
