The procedure I know is:

- Create a full color PNG image (holding your own graphic design)
- Create an indexed image of 16 colors based on your full color PNG image?
- Transform the indexed image into LSS format using the correct order
of colors. The LSS format is what isolinux finally reads, not the PNG
image. If the order of colors is not the same in both the indexed
image and the LSS image, the final result may not be displayed as you

There is some automation around this at:
