description	Build a reusable brand color system from Chinese traditional colors. Use when a user needs brand palette governance, color rules, identity consistency, usage ratios, forbidden combinations, cross-channel guidance, or long-term visual rules based on Chinese traditional colors.

xxd-brand-system

Purpose

Use this skill when color must become brand behavior, not just a campaign palette. It should help a team stay recognizable across website, social, product, packaging, presentation, and offline materials.

Pain Points This Solves

• Brand colors drift when every designer or campaign picks a different "Chinese" feeling.
• A palette without governance cannot tell teams what to use for hero moments, product UI, social covers, or print.
• Brand systems fail when they only describe meaning, not ratios, forbidden uses, and handoff rules.

Data Contract

• Use the bundled references inside this skill:
  • references/chinese-color-master-list.md: full 742-color Markdown source list.
  • references/chinese-color-harmony.csv: complete machine-readable harmony table for all 742 colors.
  • references/chinese-color-harmony.md: Markdown version of the same harmony relationships.
• Include color name and HEX for every color.
• If the user has existing brand colors, map them to nearest project colors and preserve recognition unless a full redesign is requested.
• If the brand becomes an interface, hand off token work to xxd-ui-token.

Brand System Workflow

1. Define brand pressure:
   • Category norms and expected colors.
   • Desired difference from competitors.
   • Price position and cultural posture.
   • Primary channels: product, website, social, print, packaging, events.
2. Decide the color governance model:
   • Anchor color: the brand's most recognizable traditional color.
   • Support family: 2 to 4 quiet colors for depth and flexibility.
   • Neutral base: canvas, text, borders, captions.
   • Accent colors: 1 or 2 high-attention colors with strict limits.
3. Assign usage by channel:
   • Website and landing pages.
   • Product UI.
   • Social and campaign assets.
   • Decks and documents.
   • Packaging or print when relevant.
4. Create rules:
   • Default ratio and hero ratio.
   • Which colors may touch the logo.
   • Which colors can carry text.
   • Which combinations are forbidden.
   • What a campaign may change without breaking the brand.
5. Add governance notes: owner, review trigger, and when to run accessibility or print checks.

Output Shape

• Brand color thesis: concrete, channel-aware, not poetic filler.
• Core palette: role, color name, HEX, ratio, brand job, channel.
• Channel rules: website, product UI, social, deck, packaging, print if relevant.
• Forbidden combinations: specific pair, proportion, or use case with reason.
• Handoff: token names, audit rules, or next skill.

Tie every color to a brand behavior. Avoid vague claims like "高级感" unless you translate it into use rules.
