effective-foreground-color

Arguments: object &key base-color scratch-rgb

Returns the color returned by foreground-color for object if that function returns a color (rather than nil). The value will be an RGB color, as returned by make-rgb.

If the scratch-rgb argument is specified, it should be a RGB object which will be modified to be the effective foreground color. This avoids consing a new RGB object.

The base-color argument is used internally and should not be specified by applications.

If foreground-color returns nil, effective-foreground-color returns the color returned by default-foreground-color for object. (As of 5.0, foreground-color returns nil when no foreground color has been explicitly assigned to an object.)
