you may just run through the list sys.argv like

for filename in sys.argv:
    plotlfile(filename, ...)

define your own favourite color-list like

my_colors = ['black', 'red', 'blue']

and afterwards circle through this like:

 for index, filename in enumerate(sys.argv):
    plotlfile(filename, ..., color=my_colors[index])
