README 文档

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];
