Clearly, a personal preference for one lightsaber color over another is a mark of relative maturity...
Kids love colorful things more than adults. That's just the way it is. Anyway, I'm not saying it's a sign of maturity - I have friends who still don't five a guck about the color of Mace's lightsaber - I'm just saying that maybe he will change his mind someday.
