Unofficial Colors

Unofficial Colors are a classification of hues, shades, and chromatic phenomena whose existence, persistence, or perception falls outside the codified spectrum recognized by the Seventy-Second Concordance. Their status is typically provisional, contested, or defined solely by negation, making them a primary subject of study for the Archive of Receding Colors and a frequent point of contention within Marginalia on color-related documents.

Definition and Scope

An Unofficial Color is any chromatic instance that fails to meet one or more of the criteria established in Clause 19 of the Seventy-Second Concordance, "On the Certification of Visual Phenomena." These criteria mandate that a color must be: (a) reproducible under standard Tower illumination (Candelabra-Grade 4), (b) unanimously identifiable by a quorum of three Certified Chromaticians, and (c) stable in perception for a minimum of forty-eight consecutive hours without documented fade. Colors that satisfy these criteria are entered into the Official Spectrum Ledger. All others are, by default, Unofficial.

The category is therefore exceptionally broad, encompassing everything from fleeting afterimages observed during Containment breaches to the "visibly absent" pigments described in the Codicil of Unspoken Colors. It also includes colors reported by a single individual (deemed "subjective hues"), colors that appear only under specific non-standard conditions such as in the Sighing Atrium's twilight, and colors that actively resist documentation, such as those held within the Archive of Receding Colors.

Major Subclassifications

The Archivists of Floor 717 maintain a working taxonomy of Unofficial Colors, though it carries no weight under the Concordances. The primary subclasses are:

• Provisional Hues: Colors undergoing evaluation. A color may remain Provisional for decades if consensus among Chromaticians cannot be reached. The pale lavender-grey purportedly visible at the exact center of a Divergent Grid has held Provisional status for 112 years.
• Receding Colors: Those documented to fade from collective perception over time, the central concern of the Archive of Receding Colors and its Receding Protocols.
• Contested Colors: Hues whose very existence is debated. Notable examples include "Administrator's Crimson" (allegedly seen only by holders of the office of High Curator) and the "Color of Unread Margins," cited in dissenting notes appended to the Ninety-Eighth Concordance.
• Conditional Colors: Colors that manifest only under precise, often unreproducible circumstances. The "Sigh-Blue" of the Sighing Atrium and the "Ink-Black of Perfect Silence" recorded in the Ledger of Initial Anomalies fall into this category.

Governance and the Negative Concordance

Unofficial Colors exist in a legal lacuna. They are not governed by the Seventy-Second Concordance, which applies only to official colors. Instead, their handling—where it is regulated at all—falls under scattered clauses in other Concordances and, most influentially, under the accumulated precedent of the Negative Concordance. This body of rulings primarily dictates what cannot be done with unofficial colors (e.g., "No pigment classified as Unofficial shall be used in the illumination of a major stairwell," Negative Concordance Ruling 44.7). The practical management of these colors, therefore, defaults to archival bodies like the Archive of Receding Colors and to the informal practices of guilds like the Lamplighters' Guild, who often develop their own nomenclature for the hues encountered in poorly lit spirals.

The Pocket Concordance of Permissive Queries includes several entries dedicated to navigating the bureaucratic ambiguity surrounding Unofficial Colors, particularly for researchers seeking access to restricted archives.

Controversy: The Legitimacy of Perception

A persistent scholarly debate, often waged within the margins of conservation reports, questions whether Unofficial Colors are a legitimate chromatic category or a bureaucratic artifact. The formalist school, led by the Chromaticians of the High Curators Spire, argues that if a color cannot be certified, it is not, for any practical archival purpose, a color at all. They consider the term "Unofficial Color" an oxymoron.

The experiential school, centered at the Archive of Receding Colors, counters that the Tower's reality is not bound by its own administrative criteria. They point to the tangible, albeit fading, artifacts in their care and to the consistent, if individual, reports from Watchers and Lamplighters. This school holds that Unofficial Colors constitute the vast, unseen majority of the chromatic world, with the Official Spectrum being merely a small, stable island within it. This debate was notably intensified following the Incident at the Central Aperture, which produced several transient hues that were widely witnessed but impossible to formally certify.

Material and Logistical Challenges

Handling Unofficial Colors presents unique difficulties. Standard preservation techniques are often ineffective or even deleterious. The Receding Protocols mandate specific procedures for slowing perceptual fade, including controlled exposure to certain patterns of shadow and the use of provisional Materialization Watches during re-concretization ceremonies. Transport of Unofficial Color samples between floors, such as from the Archive of Receding Colors to the adjacent Lost Sensations Archive, requires a dispensation citing Clause 8 of the Third Concordance and must be logged in the Ledger of Certified Vigil.

Furthermore, the creation of records poses a problem. Depicting an Unofficial Color in a report risks altering its perceived qualities or accelerating its recession. As a result, many are recorded only via descriptive text or through metaphorical or indirect references, leaving their true nature a matter of interpretation and ensuring their permanent status as "unofficial."
