Examples

You can retrieve a list of n colors by using the n_colors parameter:

import matplotlib.pyplot as plt
import seaborn as sns
import aaanalysis as aa
colors = aa.plot_get_clist(n_colors=2)
sns.palplot(colors)
plt.show()

We assembled 8 different color lists for 2 to 9 colors:

for n in range(3, 9):
    colors = aa.plot_get_clist(n_colors=n)
    sns.palplot(colors)
    plt.show()

For more than 9 colors, we provide the ‘husl’ default color palette of the :func:seaborn.color_palette function:

for n in [10, 15, 20]:
    colors = aa.plot_get_clist(n_colors=n)
    sns.palplot(colors)
    plt.show()
