code sample to change jtextpane color, font:

 

  // set on the text area.
        MutableAttributeSet attrs = jtp.getInputAttributes();

        // Set the font family, size, and style, based on properties of
        // the Font object. Note that JTextPane supports a number of
        // character attributes beyond those supported by the Font class.
        // For example, underline, strike-through, super- and sub-script.
        StyleConstants.setFontFamily(attrs, font.getFamily());
        StyleConstants.setFontSize(attrs, font.getSize());
        StyleConstants.setItalic(attrs, (font.getStyle() & Font.ITALIC) != 0);
        StyleConstants.setBold(attrs, (font.getStyle() & Font.BOLD) != 0);

        // Set the font color
        StyleConstants.setForeground(attrs, c);

        // Retrieve the pane's document object
        StyledDocument doc = jtp.getStyledDocument();

        // Replace the style for the entire document. We exceed the length
        // of the document by 1 so that text entered at the end of the
        // document uses the attributes.
        doc.setCharacterAttributes(0, doc.getLength() + 1, attrs, false);
