java - How do I change the Text Color and the Fillcolor

Question

How do I change the header font color to white and the fill green? These are the classes that I am using:

import static org.apache.poi.ss.usermodel.CellStyle.*
import static org.apache.poi.ss.usermodel.IndexedColors.*
import org.apache.poi.hssf.usermodel.*
import org.apache.poi.hssf.usermodel.HSSFWorkbook
import org.apache.poi.ss.usermodel.Cell
import org.apache.poi.ss.usermodel.CellStyle
import org.apache.poi.ss.usermodel.Row
import org.apache.poi.ss.usermodel.Sheet
import org.apache.poi.ss.usermodel.Workbook
import org.apache.poi.ss.usermodel.Font

And this is the code where, I believe, it will have to be inserted into.

Font headerFont = wb.createFont();
headerFont.setBoldweight(Font.BOLDWEIGHT_BOLD)
CellStyle headerStyle = wb.createCellStyle()
headerStyle.setFont(headerFont)

cellMOPID.setCellStyle(headerStyle)
cellType.setCellStyle(headerStyle)
cellStatus.setCellStyle(headerStyle)
cellState.setCellStyle(headerStyle)
cellStartDate.setCellStyle(headerStyle)
cellEndDate.setCellStyle(headerStyle)
cellDesc.setCellStyle(headerStyle)

     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
