The Neathbow

"A book for children. One page is devoted to each of the colours of the Neath, which are not found on the Surface."

The Neathbow is the conjectural term for seven colors which cannot be seen on the Surface. They're most commonly observed in the Neath (hence the name), but they may also turn up in places like Parabola and the High Wilderness.

Irrigo

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

The most prominent 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. Strangely, 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.

Violant

"V marks VIOLANT when blood is shed in a spired place. Violant ink is employed for the most desperate treaties..."

Violant is irrigo's counterpart; it indelibly lingers in one's memory. It's very hard to forget anything written in violant ink. Correspondants use this ink extensively in their esoteric publications, which often shake up the status quo quite well.

The name "violant" could stem from "violent," or "violet," or both.

Cosmogone

"C lights COSMOGONE, the colour of remembered suns. The fecund, the foetid, the fungal: these flourish in the glow of cosmogone."

A shade heavily associated with Parabola, cosmogone is the color of remembered sunlight. Under its light, fungus and other flora flourishes. It's the most prominent color in a Ray-Drenched Cinder, and it's the tint of a Glassman's spectacles. Cosmogone is irresistible to the denizens of the mirrors.

The name "cosmogone" probably comes from the word "cosmogony", the study of the origin of the solar system, or of the universe.

• 
  The Mirror-Marches, bathed in cosmogone light.

Peligin

"P drowns in PELIGIN, the colour of the deepest zee."

Peligin is the hue of the waters of the Unterzee and those of the land of the dead^{[citation needed]}. It's the color of the eyes of Monster-Hunters, as they have consumed the peligin flesh of zee-monsters. Peligin is a dark, dark, black, beyond the reach of any light.

The term "peligin" likely comes from the Latin pelagus, meaning the sea.

• 
  The broad, dark Unterzee.
• 
  A Hunter's Eye.

Apocyan

"A wakes APOCYAN, the blue of memory and brightest coral."

Apocyan is the color of coral, of memory, and of the Zee's waves. Chess pieces of this color are highly prized. Crooked-Crosses often lacquer their crosses in this color. And an apocyanic piece of amber may be what brings down the Bazaar...

The name "apocyan" almost certainly derives from the color cyan, which has a similar hue, and "apocalypse".

• 
  An Apocyan Chess-Piece, straight from Port Cecil.
• 
  A Crooked-Cross, lacquered in apocyan and blue.
• 
  Blue Scintillack. It blazes with apocyanic radiance.

Viric

"Behind your mirror, V names VIRIC, the colour of shallow sleep."

Viric is the green of shallow sleep. It's heavily associated with the Fingerkings — Fingerking-possessed Clay Men's (and the Somnolent Hyena's) eyes burn with viric fire, and a box of dream-snakes will also glow viric. The priests of Varchas use viric Mirror-Charms to ward off Fingerkings from their dreams.

When viric light comes into contact with vegetation, it causes it to flourish and grow at an exponential rate.[1]

The word "viric" probably comes from the Latin vivo, "alive".

  A Phantasmal Encounter, 189-, Captain ------
• 
  A Mirrorcatch Box Full of Very Angry Dream-Snakes.
• 
  The Somnolent Hyaena.

Gant

"G is lost in GANT, which remains when all other colours are eaten. Gant can be found where shadows are myriad."

The color one sees in the dark, gant is more beige than one might expect. It is the color of the Eater of Names' boat, and zee-beasts go to a place called the Gant Pole to die. Perhaps most notoriously, it is also the color of the Avid Horizon's gate. Gant ink is used to remove false tattoos; it also can be used as an invisible ink, meant for writing Licentiates' aliases.

•

Fireworks featuring the Neathbow are occasionally lit during the Feast of the Exceptional Rose to celebrate the occasion.

• Irrigo fireworks can help dull memories of hard times.
• Violant fireworks are hard to forget.
• Viric fireworks induce lassitude - sweet dreams!
• Gant fireworks show depth of feeling - grandiose but a bit arrogant.
