Token layers

  • Primitives: raw palette scales.
  • Semantic: color.text.primary, surface.canvas.
  • Component tokens only when they remove real duplication.

In code

  • CSS variables or Tailwind theme as a pragmatic source of truth.
  • Run WCAG contrast checks on semantic tokens—not only “pretty” primitives.

Common mistakes

  • Primitives: raw palette scales.
  • Semantic: color.text.primary, surface.canvas.

FAQ

Do tokens replace components?
