13 Feb 2020

Code below shows how to print out the color names and hex codes for the default Matplotlib Color Cycle.

import matplotlib.pyplot as plt

colors = plt.rcParams['axes.prop_cycle'].by_key()['color']
colors

['#1f77b4',
 '#ff7f0e',
 '#2ca02c',
 '#d62728',
 '#9467bd',
 '#8c564b',
 '#e377c2',
 '#7f7f7f',
 '#bcbd22',
 '#17becf']

plt.figure(figsize=(16,12))

for inc in range(1,11,1):
    plt.plot([1+inc,1],
             [1,1+inc],
             linewidth=12);

plt.legend(colors,
           loc='upper center')

plt.tick_params(
    axis='x',
    bottom=False,
    labelbottom=False)
plt.tick_params(
    axis='y',
    left=False,
    labelleft=False)
for spine in plt.gca().spines.values():
    spine.set_visible(False)
