You can change the background of a view by making a custom subclass of NSView and implementing this method:
This code just makes the view white, but another colour is easy to achieve by changing "whiteColor" to the color of your choosing.
Code:
- (void)drawRect:(NSRect)rect {
// Drawing code here.
NSColor *white=[NSColor whiteColor];
[white set];
NSRectFill([self bounds]);
}This code just makes the view white, but another colour is easy to achieve by changing "whiteColor" to the color of your choosing.

1. Do you get an error, or just nothing happens?
2. Can you post the actual code you're using to do it? In the example you give, the call is misspelled (but probably just a typo here?)
3. Are you sure that myWindow is a valid, initialized window? For example, is it connected to a window in IB? Are you trying to call setBackgroundColor: in a method that gets called before awakeFromNib:? If you are, the window might be invalid or not receive messages yet.

It looks like the problem is related to HiRez's #3 item. You could try NSLog-ing your myWindow variable on awakeFromNib, and see if it shows up as a valid object. If not, then there's something wrong with your nib.

Change your window style to textured. Does that work now?
Also, make sure to tell the [window display] after setting the color.
