Php library to convert between [sRGB](//en.wikipedia.org/wiki/SRGB), [XYZ](//en.wikipedia.org/wiki/XYZ_color_space), and [Lab](//en.wikipedia.org/wiki/Lab_color_space) color spaces, and calculate various [color distance metrics](//en.wikipedia.org/wiki/Color_difference) (delta E). Currently CIE76 and CIE94 are implemented, but I plan to implement more.

```php

use Danmichaelo\Coma\ColorDistance,

	Danmichaelo\Coma\sRGB;

$color1 = new sRGB(1, 5, 250);

$color2 = new sRGB(0, 0, 208);

$cd = new ColorDistance;

$cie94 = $cd->cie94($color1, $color2);

echo 'The CIE94 ∆E is ' . $cie94 . ' between ' . $color1->toHex() . ' and ' . $color2->toHex() . '.';

```
