This library helps you build an object representation of a colour out of a string (all objects are immutable). You can easily extract any information out of the colors, transform their representation and modify the colours.

It supports these formats:

- `#39f`
- `#39ff` (last hexadecimal value for the alpha)
- `#3399ff`
- `#3399ffff` (last 2 hexadecimal values for the alpha)
- `rgb()`
- `rgba()`
- `hsl()`
- `hsla()`
- `device-cmyk()`
- literals (as [defined](https://www.w3.org/wiki/CSS/Properties/color/keywords) by the W3C)

Installation
------------

[](#installation)

```
composer install innmind/colour
```

Usage
-----

[](#usage)

```
use Innmind\Colour\Colour;

$rgba = Colour::of('39f');
$hsla = Colour::of('hsl(210, 100%, 60%)');
$cmyka = Colour::of('device-cmyk(80%, 40%, 0%, 0%)');
$rgba = Colour::blue->toRGBA();
```

Each representation can be represented to the other two so you can always work with your preferred format.
