What it does

The Design Token Generator produces seeded color tokens for prototypes and theme testing — up to 100 named tokens per run, with your own prefix (e.g. --brand-), in the color format you choose, exportable as CSS variables or JSON. The same seed always regenerates the same palette of tokens, so a prototype theme stays stable across sessions.

Common use cases

  • Theme plumbing tests — verify your theming pipeline (CSS variables, context providers, token build steps) with disposable but stable values.
  • Prototype palettes — fill a design mockup with plausible token sets before the real brand colors exist.
  • Visual regression fixtures — seeded tokens keep screenshot baselines stable while still exercising varied colors.
  • Token tooling demos — sample input for style-dictionary-style pipelines and documentation.

Settings

  • How many — 1 to 100 tokens per run.
  • Prefix — the token name prefix (--color-, --brand-, theme.…).
  • Format — the color representation for each token value.
  • CSS output style — how the exported CSS block is written.
  • Seed — identical seed + settings = identical token set.

Privacy note

Tokens are generated locally in your browser and never uploaded. They are synthetic placeholder values for engineering and prototyping — not a designed, accessibility-checked palette.

FAQ

Are these colors accessible / on-brand? No — they’re random values for testing the mechanics of theming. Check contrast before shipping any generated color to real users, or design the final palette deliberately.

Why seed a color palette? Stability. A prototype that re-randomizes its theme on every build breaks visual diffs and confuses reviewers; a seeded set only changes when you change it.

How does this differ from the Palette and UI Theme tools? Palette generates harmonious color sets for design exploration; UI Theme builds a full light/dark theme; this tool emits raw named tokens for engineering pipelines.
