Emotional Spectrum

The emotional spectrum is a fictional concept in comic books published by DC Comics, especially the Green Lantern titles. The colors of the emotional spectrum are harnessed as power sources by organizations with power rings.

The emotional spectrum is divided into the seven colors of the rainbow, with each color corresponding to an emotion: rage (red), greed (orange), fear (yellow), willpower (green), hope (blue), compassion (indigo), and love (violet). The absence of color (black) is death, and the combination of colors (white) is life. The two emotions at the ends of the emotional spectrum, rage and love, have a stronger influence over their users and willpower (at the center of the spectrum) can be used to overcome and control one's emotions. More recently it was revealed that a ring was created to allow any user to harness any color of the emotional spetrum, named the Phantom Ring. Groups embodying points on the emotional spectrum are:
