README

This class is intended to make it easier to convert between colorspaces, as well as compare one color to another.

Requirements

• PHP 5.3 or greater (closure support is required)

Examples:

Initialize object (using hex notation is easier if you are familiar with CSS colors):

$color = new Color(0xFFFFFF);

Get distance from another color using the RGB colorspace:

$color1 = new Color(0xFFFFFF);
$color2 = new Color(0x888888);

$distance = $color1->getDistanceRgbFrom($color2);

Get closest matching color using the Lab(CIE) colorspace:

$color = new Color(0xFFFFFF);

$palette = array(
    0x000000,
    0x888888,
    0xAAAAAA
);

$matchIndex = $color->getClosestMatch($palette);
$matchColor = $palette[$matchIndex];
