Hi,
I changed the place of the initialization now. Still no difference.. The colors are valid. I checked this and also tried with predefined colors like [NSColor greenColor]. It seems a very strange problem to me. So am I right if I think, the colors should be drawn after they are set? Would make sense I my opinion.
Tobias

It's not unusual, it's wrong.
When the colour well's setColor: method is called, one thing it will do is invalidate itself by calling setNeedsDisplay: which will cause drawRect: to get called again, and so on - an infinite loop, potentially. I suspect Cocoa takes steps to protect itself against this sort of thing by ignoring or suppressing updates flagged from within drawRect: which may be why you don't see anything happen until a click.
Moving the set up to awakeFromNib is definitely more correct though if it's still not working then there's clearly something else going on. Are you sure the colours in the colour list are valid?
