"A wakes APOCYAN, the blue of memory and brightest coral."[1]
A color of the Neathbow, apocyan is the color of coral, of memory,[2] and of the Zee's waves.[3] The name "apocyan" presumably derives from the color cyan, which has a similar hue, and the Greek prefix apo-, meaning something between "off, away" and "descended from"[4] - like the words "apostate" (gone-away-from-a-cause) or "apocalypse" (un-covering).
Apocyanic light is difficult to contain, even in a mirrorcatch box; it seems to want to release its memory into the world.[5][6]
Apocyan has been portrayed as a variety of shades of blue, from teal[7] to azure.
Uses
Chess pieces of this color are sourced from the Principles of Coral,[8] and Crooked-Crosses often lacquer their crosses in this color.[9] Blue Scintillack is extremely valuable and shines brilliant apocyanic light.[10] And an apocyanic piece of amber may be what brings down the Bazaar...[11]
Apocyan can also be used to create "daguerrotypes" of dreams and certain memories, often by blinking in these dreams to produce flashes of apocyanic light.[12]
↑"I bring the Bazaar.", Fallen London"You paid dearly to get this apocyanic lump into the spire, and more dearly still to get it out, once it had absorbed the imprint you needed."
↑Cast a flare into the shadows., Fallen London"The torch bursts into flames, which crackle and burn fierce apocyan. The figure starts to run towards you [...] You blink. The image remains, captured. You have a new daguerrotype, a page to add to your others. You will remember this figure. Will you remember what it is they want to burn? Will you remember to flee from them?"
