       tk_setPalette, tk_bisque - Modify the Tk color palette

       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

              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
