I actually do like that color scheme, too. Maybe not the specifics, but the color schemes pretty good.
In the comics, yeah, Jade's connected to the Starheart, which is all the magic of the universe the Guardians of the Universe gathered in order to try and control "chaos". Basically, in the comics most of the time, she's a meta/mutant and doesn't even need a ring. I doubt they'll go too much into it in the show. They might not want to confuse people with that HBO Green Lantern show coming up. Or maybe they will, they've made a few deep-cut references in the show before. But, the Starheart origin was always a little strange, and a retcon from the 90s itself.
