DESCRIPTION

       The  tk_setPalette  procedure  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 tk_setPalette is invoked with a single argument, the
       argument is the name of a color to use as the normal background color;  tk_setPalette will
       compute a complete color palette from this background color.  Alternatively, the arguments
       to tk_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               foregroundselectColor
       activeForeground               highlightBackgroundselectBackground
       background      highlightColor selectForeground
       disabledForeground             insertBackgroundtroughColor tk_setPalette tries to  compute
       reasonable  defaults  for  any  options  that you do not 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, tk_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, tk_setPalette will not change it.  The default
       for an option is the one provided by the widget ([lindex [$w configure $option] 3]) unless
       tk_setPalette  has  been  run  previously,  in which case it is the value specified in the
       previous invocation of tk_setPalette.

       After modifying all the widgets in the application,  tk_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   procedure  tk_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.
