PHPColors

A series of methods that let you manipulate colors. Just incase you ever need different shades of one color on the fly.

Requirements

PHPColors requires PHP version 8.1.0 or greater.

Installation

Composer

Simply add paladinware/phpcolors to composer.json.

composer require paladinware/phpcolors

How it works

Instantiate an object of the color class with a hex color string $foo = new Color("336699"). That's it! Now, call the methods you need for different color variants.

Available Methods

darken( [$amount] ) : Allows you to obtain a darker shade of your color. Optionally you can decide to darken using a desired percentage.
lighten( [$amount] ) : Allows you to obtain a lighter shade of your color. Optionally you can decide to lighten using a desired percentage.
mix($hex, [$amount] ) : Allows you to mix another color to your color. Optionally you can decide to set the percent of second color or original color amount is ranged -100...0...100.
isLight( [$hex] ) : Determins whether your color (or the provide param) is considered a "light" color. Returns TRUE if color is light.
isDark( [$hex] ) : Determins whether your color (or the provide param) is considered a "dark" color. Returns TRUE if color is dark.
makeGradient( [$amount] ) : Returns an array with 2 indices light and dark, the initial color will either be selected for light or dark depending on its brightness, then the other color will be generated. The optional param allows for a static lighten or darkened amount.
complementary() : Returns the color "opposite" or complementary to your color.
getHex() : Returns the original hex color.
getHsl() : Returns HSL array for your color.
getRgb() : Returns RGB array for your color.

Auto lightens/darkens by 10% for sexily-subtle gradients

/**
 * Using The Class
 */

use Mexitek\PHPColors\Color;

// Initialize my color
$myBlue = new Color("#336699");

echo $myBlue->darken();
// 1a334d

echo $myBlue->lighten();
// 8cb3d9

echo $myBlue->isLight();
// false

echo $myBlue->isDark();
// true

echo $myBlue->complementary();
// 996633

echo $myBlue->getHex();
// 336699

print_r( $myBlue->getHsl() );
// array( "H"=> 210, "S"=> 0.5, "L"=>0.4 );

print_r( $myBlue->getRgb() );
// array( "R"=> 51, "G"=> 102, "B"=>153 );

print_r($myBlue->makeGradient());
// array( "light"=>"8cb3d9" ,"dark"=>"336699" )

Static Methods

hslToHex( $hsl ) : Convert a HSL array to a HEX string.
hexToHsl( $hex ) : Convert a HEX string into an HSL array.
hexToRgb( $hex ) : Convert a HEX string into an RGB array.
rgbToHex( $rgb ) : Convert an RGB array into a HEX string.

/**
 * On The Fly Custom Calculations
 */

use Mexitek\PHPColors\Color;

// Convert my HEX
$myBlue = Color::hexToHsl("#336699");

// Get crazy with the HUE
$myBlue["H"] = 295;

// Gimme my new color!!
echo Color::hslToHex($myBlue);
// 913399

CSS Helpers

getCssGradient( [$amount] [, $vintageBrowsers] ) : Generates the CSS3 gradients for safari, chrome, opera, firefox and IE10. Optional percentage amount for lighter/darker shade. Optional boolean for older gradient CSS support.

Would like to add support to custom gradient stops

use Mexitek\PHPColors\Color;

// Initialize my color
$myBlue = new Color("#336699");

// Get CSS
echo $myBlue->getCssGradient();
/* - Actual output doesn't have comments and is single line

  // fallback background
  background: #336699;

  // IE Browsers
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#8cb3d9', endColorstr='#336699');

  // Safari 5.1+, Mobile Safari, Chrome 10+
  background-image: -webkit-linear-gradient(top, #8cb3d9, #336699);

  // Standards
  background-image: linear-gradient(to bottom, #8cb3d9, #336699);

*/

However, if you want to support the ancient browsers (which has negligible market share and almost died out), you can set the second parameter to TRUE. This will output:

use Mexitek\PHPColors\Color;
$myBlue = new Color("#336699");

// Get CSS
echo $myBlue->getCssGradient(10, TRUE);
/* - Actual output doesn't have comments and is single line

  background: #336699; // fallback background
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#8cb3d9', endColorstr='#336699'); // IE Browsers
  background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#8cb3d9), to(#336699)); // Safari 4+, Chrome 1-9
  background-image: -webkit-linear-gradient(top, #8cb3d9, #336699); // Safari 5.1+, Mobile Safari, Chrome 10+
  background-image: -moz-linear-gradient(top, #8cb3d9, #336699); // Firefox 3.6+
  background-image: -o-linear-gradient(top, #8cb3d9, #336699); // Opera 11.10+
  background-image: linear-gradient(to bottom, #8cb3d9, #336699); // Standards
