Answer 1

UIManager.put("OptionPane.background", Color.WHITE); UIManager.getLookAndFeelDefaults().put("Panel.background", Color.WHITE);

Put this code before you call your JOptionPane dialog like:

UIManager.put("OptionPane.background", Color.decode("#3c6562"));
UIManager.getLookAndFeelDefaults().put("Panel.background", Color.decode("#3c6562"));
    
int input= JOptionPane.showConfirmDialog
(
   null,
   "Close the programm?",
   "Exit",
   JOptionPane.YES_NO_OPTION
 );

 if(input == 0)
 {
    System.exit(0);
 }
