There are quite a few online quizzes out there. I personally liked this one , and I got:
"Turquoise:
Turquoise-bladed lightsabers are usually less meticulously crafted or calibrated than other lightsabers, and can fail when put under too much pressure, but can also output more power than standard lightsabers. Turquoise lightsaber wielders tend to have personalities that match their more primal weapons, and they often act without first considering the consequences."
