Function parseColor

parseColor(css: string): Rgba
Resolves any colour the rendering engine accepts into sRGB.

The engine does the work: the colour is painted onto a one-pixel canvas and read back. That is deliberately not a CSS parser — it means every syntax the engine supports is supported here for free, today and after any upgrade, including lab(), oklch() and color(display-p3 …), which a hand-written parser would either miss or approximate.

Wide-gamut inputs survive: the scratch surface holds floats, so a colour beyond sRGB comes back as extended sRGB rather than clipped to the edge of it.
Parameters
- css: string
Returns Rgba
Throws
if the engine does not recognise the colour, rather than returning a misleading black.
Example
```
parseColor('rebeccapurple')            // { r: 102, g: 51, b: 153, a: 1 }
parseColor('oklch(0.7 0.2 30)')        // resolved by the engine
parseColor('color(display-p3 1 0 0)')  // { r: 278.73, … } — beyond sRGB, kept
```
