In nam trace file, every packet have an 'attribute' field, which is
produced by 'fid_' of data sources in your simulation scripts. The colors
defined by above commands builds a 1-1 mapping between colors to the
'fid's. Therefore, you may change the fid_ of your packets as a means to
label them with different colors.
You may find the details of nam trace file format in nam's man page.
Please let me know if you have further questions.
