Brand Kit

Turns a short brief into a complete, WCAG-verified brand token system — light + dark — emitted as DTCG JSON plus one theme.css.

Design & UIIntermediate★ 1,520⑂ 162AI score 8/10Last updated: Sep 16, 2026

What it does

  • Infers industry, audience, a single mood adjective and motion depth, then anchors on an aesthetic archetype.
  • Generates an OKLCH brand ramp (11 shades) plus neutrals, checking the 500 shade for 4.5:1 text contrast and 600 for 3:1 UI contrast.
  • Builds a 3-tier DTCG token set (primitive → semantic → component) covering color, type scale, 4px spacing, radius, elevation and motion.
  • Designs a real dark theme (not an inversion) and emits a single theme.css with [data-theme="dark"] overrides.
  • Verifies output via validate_tokens.py, validate_contrast.py, and validate_theme_refs.py.

Who it's for

  • Designers and frontend engineers standing up a design system from scratch or rebranding.
  • Teams tired of per-page palettes who want one themeable source of truth.
  • Products that must demonstrate WCAG AA compliance.

Examples

  1. "Fintech app, trustworthy mood — build the brand color system with dark mode" → OKLCH ramps, semantic tokens, theme.css.
  2. "Take our brand blue #2F6BFF and produce a contrast-passing token set" → ramp regeneration plus contrast report.
  3. "Check every var(--…) in our component CSS resolves" → runs validate_theme_refs.py and lists broken references.
