matplotlib.axes.Axes.legend does not recognize labelcolor as argument

Question

I'm having some trouble trying to set the color of legend entries. I want to select the same color as the line they are referring to. Here i post a runable script

import matplotlib.pyplot as plt

x, y = [1,2],[1,2]

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot(x,y,label='test',color='r')
ax.legend(labelcolor='r')

plt.show()

And that's the error I'm getting

Traceback (most recent call last):
  File "test.py", line 11, in <module>
    ax.legend(labelcolor='r')
  File "/home/username/anaconda3/lib/python3.7/site-packages/matplotlib/axes/_axes.py", line 406, in legend
    self.legend_ = mlegend.Legend(self, handles, labels, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'labelcolor'

However I saw in the legend documentation that labelcolor should work as argument. Do you have any suggestions?

Thank you in advance

Upgrade matplotlib to version 3.3.0

Then try it again.

import matplotlib.pyplot as plt

x, y = [1,2],[1,2]

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot(x,y,label='test',color='r')
ax.legend(title='Guide', labelcolor='red')

plt.show()
