Problem
OpenBook's colour system is inconsistent: the sidebar renders only a pale hue-tint of the accent (never the colour itself), and tag/chart/status colours live in 5 divergent hardcoded lists (pastel chips vs saturated dots, duplicated chart + status palettes). Board: OB-375 (spike for Epic OB-374).
Solution
Docs-only spike deliverable:
docs/design/colour-consistency-manifest-2026-07.md— the authoritative, owner-signed-off spec for OB-377/378/379:--sheet-veilhover/active/press, intensity 0–3 mapping, neutral--desktoken, migration note.docs/design/ob-375-palette-audit.mjs, standalone node script that re-emits every table): 68/68 sidebar fg pairs, 102/102 washed states, all chip pairs ≥4.5:1; per-theme overrides included.dataColorsappearance option, canonicalpackages/sdk/src/dataColors.tsmodule, CSS-vars-at-runtime / inline-at-export rule.New deps: none.
Before / After
