Announcing Colorcet 3.0! Thanks to Peter Kovesi and Randy Pittman, [colorcet.holoviz.org](http://colorcet.holoviz.org) now has 23 new perceptually uniform colormaps for Python, including Rainbow4 (a drop-in replacement for Jet), Gouldian (a better Parula), 15 new cyclic maps, and 5 new colorblind-safe maps.

Colorcet provides 100+ Bokeh, Matplotlib, or numerical colormaps, each derived from rigorous models of human vision to achieve either perceptual uniformity (for continuous colormaps), or perceptual distinctiveness (for 256-color categorical color sets).
