rahrah 0.6.1

University-inspired matplotlib color palettes and colormaps. Colors are taken directly from University branding guidelines, so there is no specific effort toward perceptual uniformity or accessibility for color blindness beyond the aesthetic choices I made in putting the palettes/colormaps together. Please check your plots/figures with COBLIS or similar.

Installation

To install:

cd ~

git clone git@github.com:avapolzin/rahrah.git

cd rahrah

sudo python3 setupy.py install

or

pip install rahrah

If you use this package or the scripts in this repository in a publication, please add a footnote linking to https://github.com/avapolzin/rahrah and/or consider adding this software to your acknowledgments. If you would like to cite rahrah, please use the Zenodo DOI linked here.

I'd love to feature plots/figures that make use of these palettes in the wild, so should these palettes be of use, please send me a copy of that figure and/or a link to your paper or presentation and I will share it here.

(Interested in palettes and colormaps based on album covers? Check out albumpl.)

There are also some alternative colormaps that are not the default associated with a specific palette, but are still callable.

How to use rahrah:

• To list all palettes and their properties:

from rahrah.palette import list_palettes

list_palettes()

You can also filter for number of colors in the color cycle or type of colormap (sequential/diverging) with the arguments mincolors and maptype.

• To list all colormaps:

from rahrah.cmap import list_maps

list_maps()

• To set palette as default for both color cycle and colormap:

from rahrah.palette import set_default

set_default('Northwestern')

• To set a palette as default for color cycle or colormap:

from rahrah.palette import set_default_ccycle, set_default_cmap

set_default_ccycle('ChicagoBright')

or

set_default_cmap('Yale')

• To access colormaps without setting them as default:

import matplotlib.pyplot as plt
import rahrah.cmap

plt.imshow(image, cmap = 'USC')

To reverse the colormap, simply append '_r' to the name (e.g., 'USC' becomes 'USC_r').

• To access the colors in a color cycle/palette without setting a default:

from rahrah.palette import return_colors

return_colors('BrownBright')

The lightness of all colormaps is shown below (all sequential maps are shown dark-to-light for easier comparison):
