This extension simply extends CInputWidget to provide Farbtastic.
Works with Yii 1.1.x.
It's really just a CInputWidget with a couple of asset manager calls. It assumes existing field values to be of type '#ff00ff' including the hash mark, and the view isn't exactly good, but it works fine with wide form. Modify according to taste.
$this->widget('ext.farbtastic.Farbtastic', array('model'=>$somemodel, 'attribute'=>'colorattr'));
