What is a Design Token? Export Colors for Dev Handoff

Design tokens are the named values that define your design system — colors, spacing, typography, and more. They're the bridge between design and code.

What Are Design Tokens?

A design token is a named key-value pair that stores a design decision:

{
  "color-primary": "#2D5BFF",
  "color-surface": "#FFFFFF",
  "color-text":    "#1A1A2E"
}

Instead of hardcoding #2D5BFF everywhere, you use var(--color-primary). When the brand color changes, you update one value — not hundreds.

Why Tokens Matter for Dev Handoff

Without tokens, designers write "use this blue" and developers guess. With tokens:

• Designer defines: button-primary-bg = color-brand-600
• Developer implements: background: var(--button-primary-bg)
• Same language, zero ambiguity

Token Formats

CSS Custom Properties

:root {
  --color-primary:   hsl(225, 95%, 58%);
  --color-secondary: hsl(262, 80%, 58%);
  --color-surface:   hsl(0, 0%, 100%);
  --color-text:      hsl(225, 25%, 12%);
}

Tailwind Config

module.exports = {
  theme: {
    extend: {
      colors: {
        primary: 'hsl(225, 95%, 58%)',
        secondary: 'hsl(262, 80%, 58%)',
      }
    }
  }
}

JSON (for Figma, Style Dictionary, etc.)

{
  "color": {
    "primary": { "value": "#2D5BFF" },
    "secondary": { "value": "#6B2DFF" }
  }
}

Token Naming Best Practices

Semantic naming beats literal naming:

/* ❌ Literal — breaks when you change colors */
--blue-500: hsl(225, 95%, 58%);

/* ✅ Semantic — survives redesigns */
--color-action-primary: hsl(225, 95%, 58%);
--color-surface-raised: hsl(0, 0%, 100%);
--color-text-primary:   hsl(225, 25%, 12%);

FAQs

What's the difference between a design token and a CSS variable? A CSS variable is a technical implementation. A design token is a semantic design decision. Tokens are often implemented as CSS variables, but they can also be Sass variables, JS constants, or JSON.

Do I need a tool like Style Dictionary? For large teams and multi-platform (web + iOS + Android) design systems, yes. For most web projects, CSS variables are sufficient.

Should tokens include spacing and typography too? Yes. A complete token system covers color, spacing, typography, shadows, border-radius, and animation timing. Start with color — it's the highest-impact token category.
