Question

i can’t change the color of text button using L&F. I’m using this code

UIManager.getLookAndFeelDefaults().put("Button.background", Color.ORANGE);
UIManager.getLookAndFeelDefaults().put("Button[Default+Pressed].textForeground", Color.BLUE);    
UIManager.getLookAndFeelDefaults().put("Button.foreground", Color.BLUE);    
UIManager.getLookAndFeelDefaults().put("Button[Disabled].textForeground", Color.BLUE);    
UIManager.getLookAndFeelDefaults().put("Button.disabled", Color.BLUE);    
UIManager.getLookAndFeelDefaults().put("Button.disabledText", Color.BLUE);    

The background is correctly Orange, but the text color is Black default
