+New more-accessible color cycle
+-------------------------------
+
+A new color cycle named 'ccs10' was added. This cycle was constructed using a
+combination of algorithmically-enforced accessibility constraints, including
+color-vision-deficiency modeling, and a machine-learning-based aesthetics model
+developed from a crowdsourced color-preference survey. It aims to be both
+generally pleasing aesthetically and colorblind accessible such that it could
+serve as a default in the aim of universal design. For more details
+see `Petroff, M. A.: "Accessible Color Sequences for Data Visualization"
+<https://arxiv.org/abs/2107.02270>`_ and related `SciPy talk`_. A demonstration
+is included in the style sheets reference_. To load this color cycle in place
+of the default::
+
+  import matplotlib.pyplot as plt
+  plt.style.use('ccs10')
