• MouseOverForegroundBrush - It defines the foreground color to be applied to the toolbar element on mouse hover.
• PressedForegroundBrush - It defines the foreground color to be applied to the toolbar element on mouse left click.
• MouseOverBrush - It defines the background color to be applied to the toolbar element on mouse hover.
• PressedBrush - It defines the background color to be applied to the toolbar element on mouse left click.
