A color blind/friendly color cycle for Matplotlib line plots. Might want to shuffle it around a bit more,but already not it gives kinda good contrasts between subsequent colors, and shows reasonably well in colorblind filters (though not in pure monochrome).

CBcolors.py

CB_color_cycle = ['#377eb8', '#ff7f00', '#4daf4a',
                  '#f781bf', '#a65628', '#984ea3',
                  '#999999', '#e41a1c', '#dede00']

Note that this list describes "category-10"

• https://scottplot.net/cookbook/4.1/colors/#category-10

... and there is a related list with 20 unique colors

• https://scottplot.net/cookbook/4.1/colors/#category-20

Funny enough: matplotlib has already implemented the category10 color as a standard mode in version 2.0.

however if you do something like this:

matplotlib.pyplot.plot(x,y, color = 'blue')

the old basic color will be used. So beware. New notation of category10 is as shown here:

matplotlib.pyplot.plot(x,y, color = 'C0')

Just for the sake of completeness in case someone stumbles over this old question like I did today.
Thanks for your answer @swharden , without it I wouldn't know category10 colors.
