 Wrapping colormaps
 ------------------
 
-Two new colormaps named 'twilight' and 'sunlight' were added. These
-colormaps start and end on the same color, and have two symmetric
-halves with equal lightness, but diverging color. Since they wrap
-around, they are a good choice for cyclic data such as phase angles,
-compass directions, or time of day. Like viridis, twilight and
-sunlight are perceptually uniform and colorblind friendly.
