Tiggering change event after manually setting color is returning null for color param

[Kenshinofkin]

I have a few spectrum color pickers with change events to update elements on a page. This works fine but if I manually set the color picker and try to call trigger('change') the event fires but the color parameter is null. Is there no way to trigger the change event manually?
