Irrigo

"I is for IRRIGO. No one remembers why. Irrigo colours the forgotten corners of home."

The most easily found color of the Neathbow, irrigo is the unremembered color, the light of absence. Exposure to it causes severe memory loss, overexposure to it can result in total ego death, and it can cause thick, bony plates to grow over one's eyes, creating disgusting eyeless skulls. The Cave of the Nadir is filled with dangerous irrigo radiation, so explorers use tea brewed from Ray-Drenched Cinders to protect themselves.

Irrigo can be infused into objects, and Midnighters use shrines and robes that are draped in this color to perform their rites. The Irrepressible notably uses powerful irrigo weaponry. Irrigo seems to internally retain the memories it steals, so Fluke-Cores often have years worth of histories and experiences stored within them.

Irrigo's name comes from the Latin irrigo, meaning to flood or overwhelm, or, even more suitably, to diffuse or shed.
