I simply use:

colors = ['b', 'r', 'c', 'm', 'k', 'g', 'y']
symbols = ['-', '--', '-.', ':']
nc = len(colors)
ns = len(symbols)
cs = 0
cc = 0
for i in numpy.arange(len(parameters_list)):
    plt.plot(x, y, colors[cc%nc] + symbols[cs%ns], label=r'$\Delta x_{min} =
' + str(dxmin[j]) + ', N = ' + str(Ns[i]) + r'$')
    cc += 1
    if (cc == nc):
        cc = 0
        cs += 1

This will cycle through symbols when colors run out. You can indent or not
"cs" to cycle through symbols too.
