Harness brand colors

Per-harness brand-color palette used across the Apothem project website, the Apothem mark, and every architectural diagram. One source of truth — seventeen brand colors, one apothem hub.

The canonical brand-name × color-code enumerations below are wrapped in a text fence to preserve verbatim per-harness identifiers required by the palette's catalog purpose.

Apothem core

Token	Light	Dark	Use
`apothem-hub`	`#0F172A`	`#F1F5F9`	The central distribution node ("apothem") in every architectural diagram and the central hub of the Apothem mark.
`shared-profile`	`#10B981`	`#34D399`	The source-of-truth profile feeding the apothem core.

Fifteen of the seventeen harnesses are colored to match their primary brand identity. The remaining two — glm and kimi-code — do not yet have a defined brand color; their rows are added once the upstream brand color is set, per the propagation step under Updates.

Naming rationale

apothem-hub — the geometric center the name evokes (the apothem of a regular polygon points inward to its core).
shared-profile — the upstream source, distinct from any single harness color so it reads as the "input" arrow in every diagram.
Per-harness tokens mirror the harness slug used throughout the codebase (harnesses/<slug>/, the entry-point key, the CLI --harness <slug> argument). One word per concept; the same string everywhere.

Accessibility

Every light-mode token meets WCAG 2.2 AA contrast against white text (≥4.5 : 1) where the contrast permits without distorting the brand color. Where a harness's native brand color falls below the AA threshold against white text on its own (notably the amber / orange family and the sky-blue / teal family of tokens enumerated above), diagrams that need WCAG AA text-on-color contrast use the dark-mode variant (the lifted hue) as the diagram fill so the white text reads cleanly. The dark-mode column is calibrated for this purpose: every dark-mode token clears AA against white text.

Updates

The palette updates only when a harness ratifies a brand change upstream. Per-harness brand changes propagate atomically across site/app/global.css, this page, and every affected SVG master under assets/src/.
