    byte green = (byte) color.getGreen();
    byte blue = (byte) color.getBlue();
    HSSFPalette palette = workbook.getCustomPalette();


    HSSFColor c = palette.findSimilarColor(red, green, blue);
    if (c == null) {
      try {
        c = palette.addColor(red, green, blue);
      } catch (RuntimeException e) {
        c = palette.findSimilarColor(red, green, blue);
