Rewrite the DesignBook spec note to cover the released design-book npm
package and Procedural Tokens article: decision functions
(bestContrastWith, mostVivid, nth, shade), reactive graph, scope
inheritance, native-CSS rendering. Strengthen SKILL.md implementation
guidance to emit decision logic instead of frozen literals when applying
generated colors. Remove Color Router — Design Book supersedes it.

Replace the WebFetch digest with the complete verbatim transcript from the
maintainer's print-to-PDF. Adds sections the digest missed: the dated
chronological timeline (3000 BCE → today), figure specifics (Plato,
Empedocles/Aristotle, Suhrawardi, Paracelsus, Newton's 7-hue spectrum), the
Aurum Solis, modern-practice applications, and the article's own balanced
Debates & Controversies section (Kirlian-aura skepticism, cultural
over-generalization, commercial simplification, psychological vs
metaphysical). Notes the piece originated on vocal.media.

Symbolic/mystical color meaning across traditions — Egypt, Greek elements,
alchemy, Theosophy, Golden Dawn, chakras. Concrete correspondence tables:
primary hue meanings, planetary (Sun/Moon/Mars), the alchemical stages
(nigredo→albedo→citrinitas→rubedo), elemental and Hindu/Buddhist/Taoist
mappings. Framed as cultural/symbolic color, not color science, with a
caveat on "vibrational frequency" as metaphor. Downloaded primary sources:
Thought Forms (Besant & Leadbeater 1905) and The Secret Teachings of All
Ages (Hall 1928).

Two critical/art-historical color references. Fine (2022) brings the
cultural/ideological register absent from the KB: Chirimuuta's color
adverbialism, the chromophobia thesis, and 'Pink is Primary'. Gage (1993)
is the KB's most-cited source finally given its own entry, deep on
pre-modern color (Gladstone episode, Apelles' four-pigment palette,
disegno/colore, colour-music, alchemy). Cross-linked; INDEX 158->160.

Out-of-gamut color field guide — why sRGB/P3 leave a green-cyan-blue
lobe unreachable, and where to see those colors in nature (backlit
foliage, water, structural bird/butterfly color, bioluminescence,
turquoise traffic lights, 520nm green laser).
Index: new contemporary row, colour Python package + Bird Color Base
in Online Tools, file count 155 -> 156.

- Corrected spacing in author and publisher information
- Added spaces between words in various sections for improved readability
- Standardized formatting of plate references and color descriptions
- Ensured consistent presentation of color nomenclature throughout the document
Captures Jan Koenderink et al.'s recent color work: 2026 bioRxiv paper
on the empirical 3D metric field in RGB space (RGB supports ~1,000
qualitatively distinct regions; cool half coarser than warm; CIEDE2000
over-elongates ellipsoids), plus the 2022–2024 companion papers on the
not-well-tempered color circle and warm/cool as phenomenological axes.
Provides empirical grounding for hue non-uniformity and perceptual
metric field claims used elsewhere in the skill.

get correct hue-to-name mappings when working in OKLCH/HSL.
