如何将单元格的背景色设置为任何RGB值？

Question

I'm trying to set a cell background color to an RGB value like this

    XSSFCellStyle  instructionStyle = wb.createCellStyle();
    instructionStyle.setWrapText(true);
    XSSFColor myColor = new XSSFColor(new java.awt.Color(0, 73,144));
    instructionStyle.setFillForegroundColor(myColor);
    instructionStyle.setAlignment(HorizontalAlignment.CENTER);

and even it compiles aside of being horizontally align to center there is no other effect on a cell's look.can someone tell me what's wrong with this code ?Thanks
