My colleague Seb needed to convert some color values in PHP. He looked around for some good packages, but there weren't any that fit the bill. So guess what he did? He just created a new package called spatie/color.

Here's what it can do:

$rgb = Rgb::fromString('rgb(55,155,255)');

echo $rgb->red(); // 55
echo $rgb->green(); // 155
echo $rgb->blue(); // 255

echo $rgb; // rgb(55,155,255)

$rgba = $rgb->toRgba(); // `Spatie\Color\Rgba`
$rgba->alpha(); // 1
echo $rgba; // rgba(55,155,255,1)

$hex = $rgb->toHex(); // `Spatie\Color\Hex`
echo $hex; // #379bff

Currently the package only supports rgb, rgba and hex formats. If you need another format, submit a PR.
