This is a standalone composable skill. It works two ways:
/gsp-color directly for palette exploration, contrast checking, or full system design/gsp-color --enrich to add technical precision to creative color choices
Input: Hex colors, --preview, --enrich, or interactive
Output: color-system.md chunk + palettes.json (OKLCH scales)
Agent: None — inline skill, deterministic palette generation + contrast math
<execution_context> @${CLAUDE_SKILL_DIR}/chunk-format.md </execution_context>
- Always use `AskUserQuestion` for user interaction — never prompt via plain text - One decision per question — never batch multiple questions in a single message - Every palette gets the full 11-stop OKLCH scale: 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 950 - Color names must be semantic (primary, secondary, accent, neutral) not literal (red, blue) - All foreground/background pairs must report WCAG AA contrast ratios - Dark mode mapping must maintain equivalent contrast relationships - Foundation chunks follow chunk-format.md format exactly ## Step 0: Parse mode| Input | Mode | Domain |
|---|---|---|
/gsp-color #hex [#hex...] --preview | Preview scales | palette |
/gsp-color #hex [#hex...] | Generate from hex | palette |
/gsp-color --enrich | Enrich existing system | system |
/gsp-color | Interactive full system | system |
Read the domain file for the detected mode:
${CLAUDE_SKILL_DIR}/domains/palette.md${CLAUDE_SKILL_DIR}/domains/system.mdFor system mode, also read ${CLAUDE_SKILL_DIR}/references/color-composition.md.
Follow the loaded domain file's complete workflow — it contains all generation logic, API calls, output formats, and completion steps.
Write color-system.md + palettes.json to the resolved output path (skip if --preview).
Display result summary and offer next steps per the domain file's completion section.
