Usage

If you change the values of any model, the rest are automatically updated

Create

// Create an object in the standard way
$color = new \Abyrate\Colorist('rgb(55,191,0)');

// Create using static method
$color = \Abyrate\Colorist::create('rgb(55,191,0)');

Supported syntax:

• 'rgb(0,0,0)' - rgb model
• 'rgba(0,0,0,0)' - rgb model with alpha channel
• '#000000' - hex model
• '#00000000' - hex model with alpha channel
• 'orange' - name model

Range of channels:

• r, g, b - 0-255 (in the hex 00-ff)
• alpha - 0-1 (float value. In the hex 00-ff)
