I click the button foo is nil. I tried both your exact code and the

I'm trying to get the RGB components of a system color.
Which system color? Many system colors are patterns and thus do not
have real RGB values.
The doc for +controlColor says:
The system color used for the flat surfaces of a control. By
default, the control color is a pattern color that will draw the
ruled lines for the window background, which is the same as returned
by windowBackgroundColor.
If you use controlColor assuming that it is a solid, you may have an
incorrect appearance. You should use lightGrayColor in its place.
