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.
