Storing color in NSColorPboardType

SOLUTION FOUND, read edit 3

I have an nsview, and I want to be able to drag this nsview into a colorwell and make the colorwell change its color. How can I do this?

Or another question would be: how is data stored in NSColorWell for the NSColorPboardType? Because it isn't just an archived NSColor.

Hope this makes any sense

EDIT: This is a code snippet from mouseDragged in my NSView.

Code:

pb = [NSPasteboard pasteboardWithName:NSDragPboard];
[pb declareTypes:[NSArray arrayWithObjects:NSColorPboardType, NSStringPboardType, nil] owner:self];
		
[pb setString:@"test" forType:NSStringPboardType];
[pb setData:[NSArchiver archivedDataWithRootObject:[NSColor whiteColor]] forType:NSColorPboardType];
		
NSLog(@"%@", [NSColor colorFromPasteboard:pb]);

Then when I drag I get this message

Code:

-[NSKeyedUnarchiver initForReadingWithData:]: incomprehensible archive (0x4, 0xb, 0x73, 0x74, 0x72, 0x65, 0x61, 0x6d)

What am I doing wrong?

Thanks.

EDIT2: ok i found out it is supposed to be NSKeyedArchiver not NSArchiver, but NSColorWell's still don't do anything when I drag to it

EDIT3: the problem was that I had this in my NSView

Code:

- (unsigned int)draggingSourceOperationMaskForLocal:(BOOL)isLocal
{
	return NSDragOperationCopy;
}

once i commented that out everything worked perfectly

 

Sorry, I meant that I have this NSView, and when I drag it, a colored square box appears (just like when you drag from NSColorWell). I want to be able to make it so when you drop that square box in an NSColorWell, it will change the colorwell into a certain color.
