Re: problem with colors in nam

[Haobo Yu <haoboy@isi.edu>]

The problem is because although nam allows one to assign color index
higher than 256, all packet flow ids are truncated to less than 256 when
converted to color index. Therefore, the color index may not match the
big flow ids. 

Sorry I don't know if there is an easy fix.
