Swing : font color & strike color in JTextPane

I have a JTextPane in which text color is set as blue by default. Now i added strike-through on text then strike-through color becomes as same of text (blue). I want the color of text and strike-through different. e.g. if text color is blue then the strike-through must be different.

Please give me some idea.

    JTextPane text = new JTextPane();

    Font font = new Font("Serif", Font.ITALIC, 20);
    text.setFont(font); 

    text.setForeground(Color.BLUE); 

    Style style = text.addStyle("Bold", null);
    StyleConstants.setStrikeThrough(style, true);

    text.setCharacterAttributes(style, false);

I think this should do the trick...

MutableAttributeSet attributes = text.getInputAttributes();
StyleConstants.setStrikeThrough(attributes , true);
StyleConstants.setForeground(attributes , Color.BLack);

StyledDocument doc = text.getStyledDocument();
doc.setCharacterAttributes(0, doc.getLength() + 1, attributes, false);
