matplotlib: plot and get_color?

Question

Is it possible to get a list of colors used in a plot? Consider this example:

line1 = ax1.plot(x1,y1)
line2 = ax1.plot(x2,y2)

I now how to set the color

plt.setp(line1,'color','red')
plt.setp(line2,'color','red')

but is there a way how to learn what color has been used? plt.getp(line1,'color') does not work and complains that

AttributeError: 'list' object has no attribute 'get_color'

Answer 1

OK, found an answer: The plot() call returns a list of lines. The correct way to query the color is

print line1[0].get_color()
