AI Design System Token Generator

Design tokens are the atomic building blocks of a design system — named values that store visual design attributes like colors, spacing, typography, and shadows. Instead of using raw values (#3B82F6, 16px, 700), tokens provide semantic names (color-primary, space-md, font-weight-bold) that can be changed in one place and update everywhere. They bridge design and development by creating a shared language.

Primitive tokens define raw values with descriptive names: color-blue-500: #3B82F6. Semantic tokens create contextual aliases that reference primitives: color-text-link: color-blue-500. This two-layer approach lets you change your entire color scheme by remapping semantic tokens to different primitives, without touching any component code. Semantic tokens also enable easy dark mode by pointing to different primitives per theme.

CSS custom properties work universally and support runtime theming. Tailwind config integrates directly with Tailwind CSS utility classes. JSON with Style Dictionary can be transformed into any target format. SCSS variables work well with traditional CSS preprocessing. For maximum flexibility, generate tokens as JSON first, then transform to your target format — this approach scales to multiple platforms.

With semantic tokens, dark mode becomes a simple token remapping. Your components reference semantic tokens like color-background-primary. In light mode, this points to white. In dark mode, it points to a dark gray. No component changes needed — just swap the token values. This architecture makes dark mode a configuration change rather than a redesign. Our generator creates both light and dark token sets.

A lean design system starts with 50-80 tokens: 20-30 colors (primary, secondary, neutrals, semantic), 8-10 spacing values, 6-8 font sizes, 3-4 font weights, 4-6 shadow levels, 3-4 border radius values, and 4-6 breakpoints. As your system matures, semantic tokens will expand to 150-300+, but the underlying primitives should stay compact. Fewer primitives means a more cohesive, manageable system.
