NAME
       Tk::palette - Modify the Tk color palette

SYNOPSIS
       $widget->setPalette(background)

       $widget->setPalette(name=>value?,name=>value ...?)

       $widget->bisque

DESCRIPTION
       The setPalette method changes the color scheme for Tk.  It does this by
       modifying the colors of existing widgets and by changing the option
       database so that future widgets will use the new color scheme.  If
       setPalette is invoked with a single argument, the argument is the name
       of a color to use as the normal background color;  setPalette will
       compute a complete color palette from this background color.
       Alternatively, the arguments to setPalette may consist of any number of
       name-value pairs, where the first argument of the pair is the name of
       an option in the Tk option database and the second argument is the new
       value to use for that option.  The following database names are
       currently supported:

	activeBackground       foreground      selectColor
	activeForeground       highlightBackground     selectBackground
	background     highlightColor  selectForeground
	disabledForeground     insertBackground	       troughColor

       setPalette tries to compute reasonable defaults for any options that
       you don't specify.  You can specify options other than the above ones
       and Tk will change those options on widgets as well.  This feature may
       be useful if you are using custom widgets with additional color
       options.

       Once it has computed the new value to use for each of the color
       options, setPalette scans the widget hierarchy to modify the options of
       all existing widgets.  For each widget, it checks to see if any of the
       above options is defined for the widget.	 If so, and if the option's
       current value is the default, then the value is changed;	 if the option
       has a value other than the default, setPalette will not change it.  The
       default for an option is the one provided by the widget
       (($w->configure('option'))[3]) unless setPalette has been run
       previously, in which case it is the value specified in the previous
       invocation of setPalette.

       After modifying all the widgets in the application, setPalette adds
       options to the option database to change the defaults for widgets
       created in the future.  The new options are added at priority
       widgetDefault, so they will be overridden by options from the
       .Xdefaults file or options specified on the command-line that creates a
       widget.

       The method bisque is provided for backward compatibility: it restores
       the application's colors to the light brown (``bisque'') color scheme
       used in Tk 3.6 and earlier versions.

BUGS
       The use of option database names rather than the configure names is
       understandable given the mechanism (copied from Tcl/Tk), but is
       potentially confusing.

       The interpolation of different 'shades' of color used for 3D effects in
       'RGB' space can lead to undesirable changes in 'hue'.  Interpolation in
       'HSV' (as used in Tk::ColorEditor) would be more robust and X11R5's
       color support probably even more so.
