You've made a yellow lightsaber
Yellow is the color of honor and loyalty. It symbolizes caution and foreboding in either direction of the blade, meaning that the owner is relatively cautious... but also to be cautious of them. Since yellow stands for both honor and cowardice, one should always think twice before attacking someone with a yellow saber.
