Design tokens are the atomic values of your design system—colors, typography, spacing, and more. This guide shows how to implement and scale design tokens effectively.
What Are Design Tokens?
Design tokens are named entities storing visual design attributes:
Token Architecture
Three-Tier Token System
┌─────────────────────────────────────────────────────────┐
│ SEMANTIC TOKENS (Component-level) │
│ button-primary-background → color-brand-500 │
│ card-shadow → shadow-md │
└─────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────┐
│ ALIAS TOKENS (Theme-level) │
│ color-brand-500 → color-blue-500 │
│ color-text-primary → color-gray-900 │
└─────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────┐
│ PRIMITIVE TOKENS (Raw values) │
│ color-blue-500 → #3b82f6 │
│ spacing-4 → 16px │
└─────────────────────────────────────────────────────────┘

Conclusion
Design tokens bridge the gap between design and development. Start with primitives, build semantic layers, and use tools like Style Dictionary to transform tokens for each platform. Consistent tokens enable scalable design systems that maintain visual coherence across products.
