如何在itext中更改列表的字体大小和颜色？

import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfWriter;

public class ChangeListFontColor {
    public static void main(String[] args) {
        Document document = new Document();

        try {
            PdfWriter.getInstance(document, new FileOutputStream("output.pdf"));
            document.open();

            List list = new List(List.ORDERED);
            list.setFirst(1);

            ListItem listItem = new ListItem();
            Paragraph paragraph = new Paragraph("List item 1");
            paragraph.setFontSize(12);
            paragraph.setColor(BaseColor.RED);
            listItem.add(paragraph);

            list.add(listItem);

            document.add(list);

            document.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
