Single plot multiple lines passing an array of colors?

Plotting two lines with a single plot command should not be easy?

import matplotlib.pyplot as plt
plt.plot([[1,2],[5,6]], c=['k','g'])

ValueError: Invalid RGBA argument

I just need two lines, one is black and the other green. What is going on here?

If you want that very much...

You can control the colors that will be cycled through using cycler. 

from matplotlib import pyplot as plt
from cycler import cycler

ax = plt.subplot(111)
ax.set_prop_cycle(cycler('color', ['black', 'green']))

ax.plot([[1,2],[5,6]])

You need to have 2 lines, not 2 points, to plot 2 lines. 

import matplotlib.pyplot as plt

plt.plot(x1, y1,  c = 'k')
plt.plot(x2, y2,  c = 'g') #x1, y1, x2, y2 should be multiple points
