@laenix thanks for the bug report. What version of matplotlib are you using?

import matplotlib

print(matplotlib.__version__)

[glenn-jocher]

@laenix could you try the following two blocks of code and see if they work for you?

Block 1

import matplotlib

def color_list():
    # Return first 10 plt colors as (r,g,b) https://stackoverflow.com/questions/51350872/python-from-color-name-to-rgb
    def hex2rgb(h):
        return tuple(int(h[1 + i:1 + i + 2], 16) for i in (0, 2, 4))

    return [hex2rgb(h) for h in plt.rcParams['axes.prop_cycle'].by_key()['color']]

print(color_list())

Block 2

import matplotlib

def color_list():
    # Return first 10 plt colors as (r,g,b) https://stackoverflow.com/questions/51350872/python-from-color-name-to-rgb
    def hex2rgb(h):
        return tuple(int(h[1 + i:1 + i + 2], 16) for i in (0, 2, 4))

    return [hex2rgb(h) for h in matplotlib.colors.TABLEAU_COLORS.values()]

print(color_list())
