Indeed I just made a new Quartz Composer application and threw
[[NSColorPanel sharedColorPanel] setShowsAlpha:YES];
into my awakeFromNib and published controls do indeed have a alpha
value with the default included QTZ. Removing that line removed the
opacity controls.

There is a setShowsAlpha method for the color panel that your color

I ran into this before and did a
[[NSColorPanel sharedColorPanel] setShowsAlpha:YES]; during
applicationDidFinishLaunching.
Solved it for me, if I recall correctly.
it's not my color well, it's the QCCompositionParameterView's color
panel. If you use that class, it handles the sliders and color well
stuff for you (among all the other mundane UI things views have to
deal with -- except resizing, it kinda messes up with that too - rdar://7304696
/ http://openradar.appspot.com/7304696 ). So while I know the
method to fix the problem, I don't have the object to do that. (of
course, I can enumerate all the app's windows, interrogate the color
panels, and change it manually myself, but that really shouldn't be
necessary).
