Optimized color schemes for data display

Project description

# color_tol: Colour maps for analysis

This Python package is meant to complement the wonderful work by [Cynthia Brewer](http://colorbrewer2.org/), using the work of [Paul Tol](https://personal.sron.nl/~pault/), where he introduced a very rigorous set of colors that were clearly identifyable for those with or without color-blindness. [His work](https://personal.sron.nl/~pault/colourschemes.pdf) can also be found under the docs folder of this package.


## Use

Three different color maps - qualitative, sequential, and diverging - are available, either in RGB or HTML codes.

To access any of them, you call the functions

qualitative(<number>)

sequential(<number>)

diverging(<number>)

where the <number> represents the number of colors you wish.

E.g.,

>>> my_map = qualitative(7)
>>> my_map.html_colors
['#332288', '#88CCEE', '#44AA99', '#117733', '#DDCC77', '#CC6677', '#AA4499']
>>> my_map.rgb_colors
[(51, 34, 136), (136, 204, 238), (68, 170, 153), (17, 119, 51), (221, 204, 119), (204, 102, 119), (170, 68, 153)]
