Since axes.color_cycle deprecated in matplotlib 2.2.0, you can edit Line 13 in mplcolors.py to colors = rcParams['axes.prop_cycle'].by_key()['color'], and it works fine for me.

The path of this file should be as below: <your_python_path>/lib/<python_version>/site-packages/fillplots/mplcolors.py for example in my Mac: ~/py/lib/python3.7/site-packages/fillplots/mplcolors.py
