Iro Supekutoru (色スペクトル, Japanese lit. for "Color Spectrum") is a variation of Reiatsu that exerts itself from a select few beings. Souls, Shinigami, Human, and Quincy are the only known beings capable of manipulating this source of energy. It revolves around the abilities of a Fullbringer, but can only manipulate the colors of the Electromagnetic Spectrum. It, in some ways, is considered the manipulation of light in a solid form.
