Tol_colors

Color schemes for lines and maps, color-blind safe

Thoses color schemes were designed by Paul Tol. This repository is only packaging his work so that it can be easily installed using pip. His work and details on how to use thoses schemes can be found on his website and in the docs directory.

Install

Using pip:

pip install tol-colors

From source:

git clone https://github.com/Descanonge/tol_colors.git
cd tol_colors
pip install .

Get started

Show the available colorsets, colormaps, and discrete rainbow colormap:

import tol_colors as tc
tc.main()

Get a colorset:

cset = tc.tol_cset('bright')

Get a colormap:

cmap = tc.tol_cmap('sunset')

See the functions docstrings for details.

To change default colorset (for lines) and colormap:

import matplotlib.pyplot as plt
import tol_colors

plt.rc('axes', prop_cycle=plt.cycler('color', list(tol_colors.tol_cset('bright'))))
plt.colormaps.register(name='rainbow_PuRd', cmap=tol_colors.tol_cmap('rainbow_PuRd'))
plt.rc('image', cmap='rainbow_PuRd')
