Color of JOptionPane border

Question

How might I go about changing the color of a JOptionPane's border?

Here is a screenshot of the border I am talking about:

enter image description here

That blue border is what I am trying to get rid of.

I tried to set UIManager.put("OptionPane.border", new BorderFactory...)for LookAndFeel but that changed the inside border, not the outermost one.

I need to get rid of that blue border.

Any ideas?

Read the JOptionPane API. It shows you how to create a JOption pane manually so that you have access to the JDialog. Once you have the JDialog you can remove the Border the same way you did in your last question:

Undecorated JDialog border

I have research on it these days, finally I found this code may help you!

UIManager.put("RootPane.frameBorder", new LineBorder(Color.red));
UIManager.put("RootPane.dialogBorder", new LineBorder(Color.red));    
UIManager.put("RootPane.errorDialogBorder", new LineBorder(Color.red));

Can you provide an explanation to the code? It might help OP or future users more that way. – Bono Sep 24 '15 at 08:40
I read the source code of alloy.jar whose JOptionPane border color is always red for error or yellow for warning. These codes tell us how to change the color of it. – Jun Dec 15 '15 at 02:37

In LaF section there is the initialization of ShadowPopupBorder which used for tooltips, popups, and modal dialogs borders. So check if it is used around your software
