Colour
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 by the W3C)
Installation
composer install innmind/colour
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.
