     HSSFCellStyle cellStyle = workBook.createCellStyle();        
     HSSFFont font = wb.createFont();
     font.setFontName(XSSFFont.DEFAULT_FONT_NAME);
     font.setFontHeightInPoints((short)10);
     font.setColor(IndexedColors.BLUE.getIndex());
     cellStyle.setFont(font);
    //the version i am using is poi-3.8
