I remember thinking there were yellow sabers in AOTC after exiting the theatre as well. Later, when I checked the DVD, I realized that it was probably just an optical illusion caused by the proximity of green sabers to yellowish sand.

Well, the movie would be just as bad no matter what colors the sabers were, so I guess it doesn't really matter.

When I was a small boy I often wondered if there was any significance in the lightsaber colors. Like maybe in the old times the color would associate you with your rank (knight, master, whatever) or if you just picked the color you like best.

And here's a question for those in the know: Didn't Mara Jade have a purple blade? I've always had that in my mind, long before Sam Jack had his, but since Ep. II, everyone talks like Sams was the first and only purple blade in the galaxy. I didn't read the comics and really can't remember seeing any art related to the character so maybe I just made that up while reading the novels long ago.
