A color system without documentation degrades over time. Team members leave and take institutional knowledge with them. New developers guess at color usage instead of following rules. The palette that was carefully built in PaletteRx slowly drifts as undocumented decisions accumulate.
What to Document
Color values: Every color's hex, HSL, and RGB values. PaletteRx's JSON export provides this automatically. Roles: Each color's semantic role and what it is used for. Usage rules: Where each color appears and where it must not appear. Contrast pairs: Which color combinations are accessible and at what WCAG level. Rationale: Why specific colors were chosen (brand strategy, competitive differentiation, accessibility requirement).
Format
Documentation should live where the team already works. A Notion page, a Confluence doc, a README in the design system repo, or a Storybook page. The format matters less than the accessibility: if the documentation exists but nobody can find it, it is useless.
Who Needs Access
Everyone who touches the visual output: designers, developers, content creators, marketing team, and any external contractors. The documentation should be understandable by non-designers ("use Primary for buttons" is clearer than "apply --color-primary with 4.5:1 contrast to interactive affordances").
Maintaining Documentation
Documentation is only valuable if it stays current. Every palette change should include a documentation update. PaletteRx's JSON export can serve as the machine-readable documentation that is always current. Pair it with human-readable usage notes that explain the "why" behind each color.
