cmcrameri 1.3

Perceptually uniform colourmaps

(PyPI)

(conda-forge)

cmcrameri

This is a Python wrapper around Fabio Crameri's perceptually uniform colour maps

http://www.fabiocrameri.ch/colourmaps.php

All credit for creating the colourmaps to Fabio. Any errors in the Python implementation of colourmaps are my own.

This version is based on Scientific Colourmaps Version 7.0 (02.02.2021)

Install

With pip:

pip install cmcrameri

With conda:

conda config --add channels conda-forge
conda install cmcrameri

Usage example

from cmcrameri import cm
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 100, 100)[None, :]  
plt.imshow(x, aspect='auto', cmap=cm.batlow) # or any of the other colourmaps made by Fabio Crameri
plt.axis('off')
plt.show()

Extra instructions

You can access all the core colourmaps from Fabio Crameri's list by cm.<colormapname>

You can use tab autocompletion on cm if your editor supports it

For a reversed colourmap, append _r to the colourmap name

Categorical colormaps have the suffix S

For an image of all the available colourmaps without leaving the comfort of your Python session

from cmcrameri.cm import show_cmaps 
show_cmaps()

To make the underlying RGB values available, the original text files are shipped as part of the package. Find them on your system with:

from cmcrameri import cm
cm.paths
