After his Rebirth, Green Lantern opened up the spectrum of light. No longer were there just GREEN Lanterns that wield willpower. But Yellow (fear), Pink (love), Red (rage), Blue (hope), and Orange (greed). Unfortunately most of them don't exactly blend together.
This is a big episode where we cover the story arcs: Mystery of the Star Sapphires, The Sinestro Corps War, Rage of the Red Lanterns, and Agent Orange. As well as some material from Wanted: Hal Jordan, Secret Origin, and Alpha Lanterns. Basically all you need to understand the full range of the emotional spectrum.
