JosephBARBIERDARNAL/pypalettes: A large (+2500) collection of color maps for Python

A large (+2500) collection of color maps for Python.

• All available palettes can be found in the Color Palette Finder.
• To learn more about how to use pypalettes, please refer to the official documentation.

This package is based on the R package paletteer, and all associated sub-packages (with original palettes) mentioned in the LICENSE file.

With pip:

With conda:

conda install conda-forge::pypalettes

Once pypalettes is imported, all the palettes are now accessible as any other colormap in matplotlib or seaborn via the palette or cmap arguments.

import matplotlib.pyplot as plt
import numpy as np
from pypalettes import load_cmap

cmap = load_cmap("Sunset2", cmap_type="continuous")

data = np.random.randn(20, 20)

plt.imshow(data, cmap=cmap)
plt.colorbar()

import matplotlib.pyplot as plt
import seaborn as sns
from pypalettes import load_cmap

cmap = load_cmap("Fun")
palette = cmap.colors # return colors as a list of hexadecimal values

df = sns.load_dataset("penguins")

g = sns.lmplot(
    data=df,
    x="bill_length_mm",
    y="bill_depth_mm",
    hue="species",
    palette=palette,
)

import matplotlib.pyplot as plt
from pypalettes import create_cmap
import numpy as np

cmap = create_cmap(
    colors=["#D57A6DFF", "#E8B762FF", "#9CCDDFFF", "#525052FF"],
    cmap_type="continuous",
)

x = np.linspace(0, 20, 1000)
y = np.sin(x)

plt.scatter(x, y, c=y, cmap=cmap)
plt.colorbar()

Going further

• Add +2500 native palettes to matplotlib and seaborn
• Load, customise and combine +2500 palettes
• Create your own palettes

PyPalettes is highly inspired (and relies on for the first one) from

• the R package paletteer
• the python library palettable

A big thanks to Yan Holtz for creating the Color Palette Finder, a web app for browsing palettes
