Arguments: object
Returns the default background color for
object. This color will be used as the background
color when the value of the background-color property is
nil.
The value must be an RGB color (as returned by make-rgb). Note that the value cannot be an HLS color (as returned by make-hls). If you use HLS colors, apply hls-to-rgb to them before setting this property, and apply rgb-to-hls to get the HLS equivalent of a RGB value.
The built-in methods are specialized on the window class. Thus, for
example, the default for dialog-mixin is returned by system-dialog-background-color and
for basic-pane
is returned by system-background-color.
Contrast with the built-in method for default-foreground-color, which is the value returned by system-foreground-color whatever the type of window.
