NSColorWell and Cocos2D Layer issue - cocos2d-iphone

Question

I am tying to dynamically change my background color on the fly using an NSColorWell. I am using cocos2d framework for desktop.
I have a GLView that shows the cocos2d window and I have a NSColorwell off to the side. When I click on the color well color, I want the background to change to that color ‘on-the-fly’ so to speak.
I have all my variables in one class called settings. And my AppDeletgate has the IBActions for the NSColorWell. And the Cocos2D GLview lives in the HelloWorldLayer.
When ever I chose a color in the NSColorWell I get an exception thrown. Any idea why?
Forgive the code dump but I wanted you all to be able to see exactly what I was doing. I have tried many different methods of implementing this.
