Building a Lightsaber at Hollywood Studios

We went to Savi’s Workshop to build a lightsaber.  I was an observer while my significant other was the builder.  You choose 1 of the 4 styles, he chose power and control.  Then you choose 1 of 4 colors: blue, green, violet, and red.  There are other colors at the merchandise store that you can change them with, like yellow and white.
