## API

| name | type | default | description |
| --- | --- | --- | --- |
| `resolveCssColor` | `(value, fallback?, context?) => string` | — | Resolves var() against the document and converts oklch to hex. Returns the fallback while server-rendering. |
| `oklchToHex` | `(input: string) => string | null` | — | oklch() and oklab() to #rrggbb, in code rather than through the DOM. |
