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 7.2.0 or greater.

Installation

Composer

Simply add mexitek/phpcolors to composer.json using dev-master.

composer require mexitek/phpcolors:dev-master

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 */useMexitek\PHPColors\Color;
// Initialize my color$myBlue = newColor("#336699");
echo$myBlue->darken();
// 1a334decho$myBlue->lighten();
// 8cb3d9echo$myBlue->isLight();
// falseecho$myBlue->isDark();
// trueecho$myBlue->complementary();
// 996633echo$myBlue->getHex();
// 336699print_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 */useMexitek\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

useMexitek\PHPColors\Color;
// Initialize my color$myBlue = newColor("#336699");
// Get CSSecho$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:

useMexitek\PHPColors\Color;
$myBlue = newColor("#336699");
// Get CSSecho$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*/
