Theme Generator creates comprehensive design token systems that power consistent theming across light mode, dark mode, and branded variants.
Token Architecture
- Follows the W3C Design Tokens Community Group spec with three tiers:
- Primitive tokens — Raw values (color/blue/500: #3b82f6)
- Semantic tokens — Intent-based references (color/action/primary: {color/blue/500})
- Component tokens — Component-scoped overrides (button/background/default: {color/action/primary})
Color Science
Generates perceptually uniform color scales using OKLCH color space. Given a brand hex color, calculates a full 11-step scale (50-950) with consistent perceived lightness steps. Dark mode tokens are computed, not manually specified, using the OKLCH lightness inversion algorithm.
WCAG Compliance
Automatically checks foreground/background token pairs against WCAG 2.1 contrast requirements (4.5:1 for normal text, 3:1 for large text). Flags failing combinations and suggests compliant alternatives.
Output Formats
- CSS custom properties (`:root` and `.dark` selectors)
- Tailwind CSS `theme.extend` config
- Style Dictionary JSON for cross-platform token distribution
- TypeScript theme object with full intellisense
Framework Integration
Compatible with shadcn/ui, Radix UI, MUI, and Chakra UI token systems. Generates mapping shims for each.
Use Cases
- Generating a complete light/dark mode token set from a single brand color
- Creating Tailwind CSS theme config from Figma design token JSON export
- Building CSS custom property themes compatible with shadcn/ui component library
- Generating color scales with proper WCAG 2.1 contrast ratios
Pros & Cons
Pros
- +OKLCH-based color scales have perceptually consistent lightness steps
- +Dark mode tokens computed automatically, not manually maintained
- +WCAG contrast checking built in, not an afterthought
- +Three-tier token architecture scales from small projects to design systems
Cons
- -OKLCH color space requires modern browser support (baseline 2023)
- -Style Dictionary output requires additional build pipeline setup
