Creating custom color styles for an XSSFWorkbook in Apache POI 4.0

To apply a custom color for an XSSFWorkbook in Apache POI 3.7 and below the following was possible:

java.awt.Color c = new java.awt.Color (1,2,3)
XSSFCellStyle xcs = xssfWorkbook.createCellStyle();
XSSFFont headerFont = xssfWorkbook.createFont();
headerFont.setColor(new XSSFColor(c));
xcs.setFont(headerFont);
cell.setCellStyle(xcs);

In version 4.0 XSSFColor(java.awt.Color) got removed. It is still possible to achieve the same, just with additional 'hackery':

XSSFColor xc = new XSSFColor();
xc.setARGBHex(String.format("%02x%02x%02x",c.getRed(),c.getGreen(),c.getBlue())); 
headerFont.setColor(xc);

But what is the 'proper' way to do this? Most of the XSSFColor methods involve an IndexedColorMap but I could not find any example for how this could be used for setting custom colors in an XSSFWorkbook.

    XSSFFont font = workbook.createFont();      
    byte[] rgb = {20, (byte) 230, 25};
    XSSFColor xc = new XSSFColor(rgb, null);
    font.setColor(xc);

Above should be the best way for POI4.*.

byte[] rgb = {120, 100, (byte) 200};
headerFont.setColor(new XSSFColor(rgb, new DefaultIndexedColorMap()));
