Getting an instance of the farbtastic object

[danielsedlacek]

It took me some time to find out how to call the methods like .setColor(string).

It would be great if you could update the documentation for others to specify how to get the instance of the farbtastic object where you call the method.

$('#placeholder').farbtastic('#input-field');
var picker = $.farbtastic('#placeholder');
picker.setColor('#FFFFFF');
