Yes, I had done that before also to no avail. But thinking I might
have been tired and erred I have done it again.
Still does not work. I am including the code and a link to a debug
picture that shows all is set correctly (as far as I can tell).
Would someone be willing to run this code and post results?
Might Apple comment or weigh in on this?

The code: (in this example I moved cp to be an ivar thinking there was
some scope issue)
NSColorPanel* cp;
- (IBAction)color:(id)sender {
cp = [NSColorPanel sharedColorPanel];
[cp setDelegate:self];
[cp setTarget:self];
[cp setAction:@selector(changeColor:)];
[cp setContinuous:YES];
[NSApp runModalForWindow:cp];
[cp orderOut:cp];
}
- (void)changeColor:(id)sender {
NSLog(@"changeColor");
}
- (void)windowWillClose:(NSNotification *)notification {
[NSApp stopModalWithCode:0];
}

Ah, your reply prompted me to review the documentation, which I
believe is in error.
It's not the delegate that gets sent this message, it's the panel's
target. use -setTarget: instead. -changeColor: is also sent to the
responder chain regardless.
The documentation lists -changeColor: under "delegate methods" but
the panel only inherits the delegate methods of NSWindow, etc.

Well, no.
I have run it
modal from a modal panel
non-modal from a modal panel
non-modal from a non-modal panel
changeColor is never called.
I am stumped and going to pour a glass of wine and play a game of
chess !

Generally apps don't run the color panel modally. I believe there
is a way to do it, I've seen it in some apps with an added OK/
Cancel button, though it seems rare and weird. It may be that
running it this way works differently, or maybe what you're doing
is just unsupported.
