### Parsing
|
||
|
|
|
||
|
|
```js
|
||
|
|
colorString.get('#FFF') // {model: 'rgb', value: [255, 255, 255, 1]}
|
||
|
|
colorString.get('#FFFA') // {model: 'rgb', value: [255, 255, 255, 0.67]}
|
||
|
|
colorString.get('#FFFFFFAA') // {model: 'rgb', value: [255, 255, 255, 0.67]}
|
||
|
|
colorString.get('hsl(360, 100%, 50%)') // {model: 'hsl', value: [0, 100, 50, 1]}
|
||
|
|
colorString.get('hwb(60, 3%, 60%)') // {model: 'hwb', value: [60, 3, 60, 1]}
|
||
|
|
|
||
|
|
colorString.get.rgb('#FFF') // [255, 255, 255, 1]
|
||
|
|
colorString.get.rgb('blue') // [0, 0, 255, 1]
|
||
|
|
colorString.get.rgb('rgba(200, 60, 60, 0.3)') // [200, 60, 60, 0.3]
|
||
|
|
colorString.get.rgb('rgb(200, 200, 200)') // [200, 200, 200, 1]
|
||
|
|
|
||
|
|
colorString.get.hsl('hsl(360, 100%, 50%)') // [0, 100, 50, 1]
|
||
|
|
colorString.get.hsl('hsla(360, 60%, 50%, 0.4)') // [0, 60, 50, 0.4]
|
||
|
|
|
||
|
|
colorString.get.hwb('hwb(60, 3%, 60%)') // [60, 3, 60, 1]
|
||
|
|
colorString.get.hwb('hwb(60, 3%, 60%, 0.6)') // [60, 3, 60, 0.6]
|
||
|
|
|
||
|
|
colorString.get.rgb('invalid color string') // null
|
||
|
|
```
|
||
|
|
|
||
|
|
### Generation
|
||
|
|
|
||
|
|
```js
|
||
|
|
colorString.to.hex([255, 255, 255]) // "#FFFFFF"
|
||
|
|
colorString.to.hex([0, 0, 255, 0.4]) // "#0000FF66"
|
||
|
|
colorString.to.hex([0, 0, 255], 0.4) // "#0000FF66"
|
||
|
|
colorString.to.rgb([255, 255, 255]) // "rgb(255, 255, 255)"
|
||
|
|
colorString.to.rgb([0, 0, 255, 0.4]) // "rgba(0, 0, 255, 0.4)"
|
||
|
|
colorString.to.rgb([0, 0, 255], 0.4) // "rgba(0, 0, 255, 0.4)"
|
||
|
|
colorString.to.rgb.percent([0, 0, 255]) // "rgb(0%, 0%, 100%)"
|
||
|
|
colorString.to.keyword([255, 255, 0]) // "yellow"
|
||
|
|
colorString.to.hsl([360, 100, 100]) // "hsl(360, 100%, 100%)"
|
||
|
|
colorString.to.hwb([50, 3, 15]) // "hwb(50, 3%, 15%)"
|
||
|
|
|
||
|
|
// all functions also support swizzling
|
||
|
|
colorString.to.rgb(0, [0, 255], 0.4) // "rgba(0, 0, 255, 0.4)"
|
||
|
|
colorString.to.rgb([0, 0], [255], 0.4) // "rgba(0, 0, 255, 0.4)"
|
||
|
|
colorString.to.rgb([0], 0, [255, 0.4]) // "rgba(0, 0, 255, 0.4)"
|
||
|
