OS Themes and setting toolbar button "selected" color

questions

I’m using OS themes feature from Extended UI option in App settings. The template does only support changing the pulldown colors not toolbar colors, however I am changing the toolbar color as well with

  IF OSTheme = 'OFF' !Default Value
    ?TOOLBAR1{PROP:COLOR}=COLOR:None  
    ?ButtonPeople{PROP:COLOR}=COLOR:None 
    ?ButtonCars{PROP:COLOR}=COLOR:None
    ?ButtonChangeTheme{PROP:COLOR}=COLOR:None	
  ELSE
    ?TOOLBAR1{PROP:COLOR}=MenuStyleMgr.Theme.MenuBarNormalColorRight
    ?TOOLBAR1{PROP:COLOR}=MenuStyleMgr.Theme.MenuBarNormalColorRight
    ?ButtonPeople{PROP:COLOR}=MenuStyleMgr.Theme.MenuBarNormalColorRight
    ?ButtonCars{PROP:COLOR}=MenuStyleMgr.Theme.MenuBarNormalColorRight
    ?ButtonChangeTheme{PROP:COLOR}=MenuStyleMgr.Theme.MenuBarNormalColorRight
  END

However when I change the color of the button on the toolbar I cannot set the “selected” color i.e. when the mouse pointer is over the button. Without all these themes the button color changes when I position mouse over it. How can I set this color for a button. Been reading help but cannot find any clues.
