"We embraced the balance within the spectrum. The center color. The color of life. Green. It is the condensation of willpower, and it is what fuels the Green Lantern Corps." --Ganthet

The Green Light is the color tied to the concept of Willpower within the Emotional Spectrum.


The Green Light was created from the White Light of Life after the Darkness mangaged to split it into seven component aspects. When this color first diverged from the White Light, it became tied to the concept of willpower. Ion was the first sentient being to use its willpower, and thus tap into the power of the Green Light. Because of this, it became the living embodiment and source of willpower.
