Why this word is great
OCTARINE — [Noun] A notional extra color, distinct from those of the rainbow or normal visible light spectrum, said to be visible only to users of magic, particularly in fiction and occultism. Coined by Terry Pratchett for his Discworld series, from octa- ("eight") and -ine (a suffix used in color names), suggesting an eighth color beyond the traditional seven of the rainbow. Unlike "ultraviolet" (which denotes a real, if invisible, wavelength) or "iridescent" (which describes a shifting play of light), octarine is the hue of the impossible—singular, unyielding, and alive. It is the shimmer between the pages of a spellbook at midnight, the glow around a cat’s pupils when it stares at something unseen, the impossible greenish-purple of a wizard’s dream. A color that refuses to exist, and yet does.
