Colorcet

Colorcet is a collection of perceptually uniform and distinct colormaps for use with Python plotting programs like Matplotlib, Bokeh, HoloViews, and Datashader. It provides 256-color continuous colormaps based on Peter Kovesi's work and perceptually distinct categorical colormaps. The library is actively maintained, with the current version being 3.1.0, and receives updates for new colormaps and compatibility with the Python ecosystem.
