This example shows you Excel cell fills and colors using Apache POI.

In our example i have used all the possible colors and set it as Fills background colors of cells.

Below is the example code.

package com.java.connect.poi;
    
    import java.io.FileOutputStream;
    import java.io.IOException;
    
    import org.apache.poi.ss.usermodel.Cell;
    import org.apache.poi.ss.usermodel.CellStyle;
    import org.apache.poi.ss.usermodel.IndexedColors;
    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.xssf.usermodel.XSSFWorkbook;
    
    public class POIFillAndColorExample {
    	public static void main(String[] args) throws IOException {
    		// Create a workbook object
    		Workbook workbook = new XSSFWorkbook();
    		// Create sheet
    		Sheet sheet = workbook.createSheet();
    
    		// Create a row and put some cells in it.
    		Row row = sheet.createRow((short) 1);
    
    		// Aqua background
    		CellStyle style = workbook.createCellStyle();
    		style.setFillForegroundColor(IndexedColors.AQUA.getIndex());
    		style.setFillPattern(CellStyle.SOLID_FOREGROUND);
    		Cell cell = row.createCell((short) 1);
    		cell.setCellValue("X1");
    		cell.setCellStyle(style);
    
    		// Orange "foreground", foreground being the fill foreground not the
    		// font color.
    		style = workbook.createCellStyle();
    		style.setFillForegroundColor(IndexedColors.AUTOMATIC.getIndex());
    		style.setFillPattern(CellStyle.SOLID_FOREGROUND);

    		fileOut.close();
    
    	}
    }

The generated excel files looks like below images.
