This can be done in a followup, but would be nice if this got added to the following for discoverability:

* https://matplotlib.org/devdocs/users/explain/colors/colormaps.html
* https://matplotlib.org/devdocs/gallery/color/colormap_reference.html#sphx-glr-gallery-color-colormap-reference-py

• add new example to https://matplotlib.org/devdocs/gallery/style_sheets/index.html showing how to use the color-sequences Add example of petroff10 in the style sheets to show how to use the color sequence.  #28796
• add a page explaining the color sequences to https://matplotlib.org/devdocs/users/explain/colors/index.html

ETA: also I'm really psyched this is going in, thanks for your work on this folks!
