Overview

Best-effort regex/character-walk parser for Tailwind v3 config files. Extracts color entries from ‘theme.colors` and `theme.extend.colors` blocks. Handles flat scalars and one level of nested scales (per Tailwind convention: `gray: { 50: “#f9fafb” }` flattens to `gray-50`).

Known limitations (out of scope for V0):

  • Function-valued entries (‘primary: defineColor(“blue”)`)

  • Spread operators (‘…palette`)

  • require()/import() of external palettes

  • Computed keys

  • TypeScript configs with type annotations on values

For any of these the entry is silently skipped; the user is encouraged to migrate to Tailwind v4 ‘@theme` (CSS-first) which parses cleanly through the existing CSS custom property path.
