-# PHPColors [![Build Status](https://travis-ci.org/mexitek/phpColors.svg?branch=master)](https://travis-ci.org/mexitek/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 `$foo = new Color("336699")`.  That's it!  Now, call the methods you need for different color variants.
-
-## Available Methods
-- <strong>darken( [$amount] )</strong> : Allows you to obtain a darker shade of your color. Optionally you can decide to darken using a desired percentage.
-- <strong>lighten( [$amount] )</strong> : Allows you to obtain a lighter shade of your color. Optionally you can decide to lighten using a desired percentage.
-- <strong>mix($hex, [$amount] )</strong> : Allows you to mix another color to your color. Optionally you can decide to set the percent of second color or original color amount is ranged -100...0...100.
-- <strong>isLight( [$hex] )</strong> : Determins whether your color (or the provide param) is considered a "light" color. Returns `TRUE` if color is light.
-- <strong>isDark( [$hex] )</strong> : Determins whether your color (or the provide param) is considered a "dark" color. Returns `TRUE` if color is dark.
-- <strong>makeGradient( [$amount] )</strong> : 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.
-- <strong>complementary()</strong> : Returns the color "opposite" or complementary to your color.
-- <strong>getHex()</strong> : Returns the original hex color.
-- <strong>getHsl()</strong> : Returns HSL array for your color.
-- <strong>getRgb()</strong> : Returns RGB array for your color.
-
-> Auto lightens/darkens by 10% for sexily-subtle gradients
-
-```php
-/**
- * Using The Class
- */
-
-use Mexitek\PHPColors\Color;
-
-// Initialize my color
-$myBlue = new Color("#336699");
-
-echo $myBlue->darken();
-// 1a334d
-
-echo $myBlue->lighten();

-## Static Methods
-- <strong>hslToHex( $hsl )</strong> : Convert a HSL array to a HEX string.
-- <strong>hexToHsl( $hex )</strong> : Convert a HEX string into an HSL array.
-- <strong>hexToRgb( $hex )</strong> : Convert a HEX string into an RGB array.
-- <strong>rgbToHex( $rgb )</strong> : Convert an RGB array into a HEX string.
-
-```php
-/**
- * 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
-- <strong>getCssGradient( [$amount] [, $vintageBrowsers] )</strong> : Generates the CSS3 gradients for safari, chrome, opera, firefox and IE10. Optional percentage amount for lighter/darker shade. Optional boolean for older gradient CSS support.
-
-> Would like to add support to custom gradient stops
-
-```php
-
-use Mexitek\PHPColors\Color;
-
-// Initialize my color
-$myBlue = new Color("#336699");
-
-// Get CSS
-echo $myBlue->getCssGradient();
-/* - Actual output doesn't have comments and is single line
-
-  // fallback background
-  background: #336699;
-
-  // IE Browsers
-  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#8cb3d9', endColorstr='#336699');
-
-  // Safari 5.1+, Mobile Safari, Chrome 10+
-  background-image: -webkit-linear-gradient(top, #8cb3d9, #336699);
-
-  // Standards
-  background-image: linear-gradient(to bottom, #8cb3d9, #336699);
-
-*/
-
-```
-
-However, if you want to support the ancient browsers (which has negligible market share and almost died out), you can set the second parameter to `TRUE`. This will output:
-
-```php
-
-use Mexitek\PHPColors\Color;
-$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
