Please note that py-af-colours has been superceded by afcharts, a python package which expands on the functionality of py-af-colours, and automates the implementation of much of the Analysis Function accessibility guidance. As such, py-af-colours is no longer being supported.
py_af_colours aims to support the creation of accessible Python graphs across the UK Government Analysis Function by simplifying access to the standard colour palettes.
If you're an R user, check out afcharts.
