- "Like willpower, fear is one of the seven living and breathing energies that form the spectrum. The color of terror. Yellow." --Ganthet
The Yellow 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 emotion of fear. Parallax was the first sentient being to experience fear, and thus tap into the power of the Yellow Light. Because of this, it became the living embodiment and source of the emotion.
- Blue Light - Amounts of the Yellow Light can be severely weakened by amounts of the Blue Light of Hope.
