Visual representation of the *emergency* colormap. Statistics of the *emergency* colormap.

The emergency colormap is a visual representation of the emergency warning lights on emergency vehicles in many countries. Unlike many other diverging colormaps, emergency is a cyclic colormap, covering the full lightness range and using the colors red and blue. Because emergency is a cyclic colormap that is CVD-friendly, it is the main colormap to use for plots with cyclic or periodic information.
