Pigment - A simple PHP library for color generation and manipulation

Pigment is a simple PHP library for color generation and manipulation. It can be used to generate gradients from two hexadecimal sources. It can also be used to manipulate colors (e.g. to make them lighter or darker).

Installation

You can install this library via Composer:

composer require c4n4r/pigment

Usage

Create a pigment instance

use Pigment\Pigment;
$pigment = new Pigment('#ff0000');

//or generate a random color

$pigment = Pigment::random();

$pigment->getHex(); // #ff0000
$pigment->getRgb(); // ["red" => 255, "green" => 0, "blue" => 0]

Darken or lighten a color

use Pigment\Pigment;

//darken by 10%
$pigment = new Pigment('#007D64');
$pigment->darken(10); //#00715a

//lighten by 10%
$pigment = new Pigment('#007D64');
$pigment->lighten(10); //#008a6e

You can also generate a gradient between two colors

use Pigment\Pigment;
$colorOne = new Pigment('#007D64');
$colorTwo = new Pigment('#ff0000');

//create a gradient with 10 steps
$gradient = $colorOne->gradient($colorTwo, 10);

Every method that manipulates a color returns a new Pigment class instance.

Use methods directly from the PigmentColorHandler class

use Pigment\Handlers\PigmentColorHandler;

$colorHandler = new PigmentColorHandler();

//darken by 10%
$darkenedColor = $colorHandler->darken('#007D64', 25);
$lightenedColor = $colorHandler->lighten('#007D64', 25);

//create a gradient with 10 steps
$gradient = $colorHandler->createGradientBetweenToColors('#007D64', '#ff0000', 10);

Those methods do not return a new Pigment class instance, you can use them if you don't need to manipulate the color further.

Transform colors in different formats

You can use the ColorTransformer class to transform colors in different formats without using a Pigment class.

$colorTransformer = new ColorTransformer();

//hex to rgb
$colorTransformer->explodeToRgb('#007D64');

//rgb to hex
$colorTransformer->implodeToHex([0, 125, 100]);

//rgb to hsl
$colorTransformer->rgbToHsl([0, 125, 100]);

//hsl to rgb
$colorTransformer->hslToRgb();
