BackgroundColor$; ForegroundColor$
Setting BackgroundColor$ sets the color of the background of the window, and of groupboxes, checkboxes, radiobuttons and statictext controls.  Setting the ForegroundColor$ sets the color of text displayed in all controls.  Only the last ForegroundColor$ and BackgroundColor$ values set before a window is opened are valid for that window.  Other special color variables exist for setting the background color of several widgets:

  TextboxColor$
  ComboboxColor$
  ListboxColor$
  TexteditorColor$

The value of the TextboxColor$, TexteditorColor$, ListboxColor$ or ComboboxColor$ variable can be changed in between each control statement.  A control will be colored according to the last color statement listed before the command to create the control.
