# Color Intelligence 3.0
Translate brand attributes to constrained palette objectives, not simplistic color psychology claims. Build OKLCH neutral ramp and accents using gamut mapping into sRGB; generate 5 alternatives with role tokens. Calculate contrast for every foreground/background pair (WCAG 2.2 text and UI), CVD simulation, light/dark parity, forced-colors mode and P3 support. Recommend by explicit weighted score plus human review.
## Workflow
1. Record explicit project requirements, business goal, content and accepted test budget.
2. Read `references/HANDBOOK.md` and pick precise technique Skill files, not the entire catalog.
3. Implement smallest meaningful working baseline, then add incremental enhancements.
4. Measure or inspect result with real devices and produce fallback.
5. Report verified/untested results. No MCP, no destructive overwrites.
## Core obligations
Generate semantic tokens in OKLCH, map into sRGB, compute contrast table and score 5 palette candidates.
Verify contrast for text/action borders/focus; simulate CVD, enforce brand override and check dark/light.
## References
- `references/HANDBOOK.md` — full architecture and 13 deep techniques.
