They've been mentioned, but let's tie them to specific characters.
The
Emotional Spectrum is a Green Lantern concept. Green is Willpower and the original force up until Geoff Johns got ahold of the property. The full list.
- Red - Rage
- Orange - Greed
- Yellow - Fear
- Green - Willpower
- Blue - Hope
- Indigo - Compassion
- Violet - Love
- Black - Death
- White - Life
Each has it's own version of the Corps, though they differ in motive and operation. Orange, for example, has only one wielder - Larfleeze - but his "Corps" consists of hard light constructs that take the form of others the ring/battery has consumed.
The Green is unrelated to Green Lantern and is actually the force that empowers the Swamp Thing, Poison Ivy, and Earth 2's Green Lantern. Like GL's Emotional Spectrum, there are competing forces, which in this case are elemental.
- The Green - Plant Life
- The Red - Animal Life (Animal Man, Vixen, Beast Boy)
- The Clear - Aquatic Life (Aquaman, actually unclear since they haven't brought up his use in New 52)
- The Grey - Alien Fungal Life
- The Rot - Decay and Death (Anton Arcane)
The Lords of Chaos and Order are pretty straightforward. The Lords of Order want to bring order and stability to the universe, The Lords of Chaos seek to bring change and discord. While this seems to be a good and bad split, taken on their extremes, you have unending stagnation versus complete anarchy. The known Lords of Order include Nabu (who powers/possesses Doctor Fate), Amethyst, and Mordru. Known Lords of Chaos include Kestrel, Kid Eternity, and Dan Didio.
The best known heroes powered by Chaos and Order are Hawk and Dove respectively.
