Reverse colormap in matplotlib

Question

I would like to know how to simply reverse the color order of a given colormap in order to use it with plot_surface.

Answer 1

In matplotlib a color map isn't a list, but it contains the list of its colors as colormap.colors. And the module matplotlib.colors provides a function ListedColormap() to generate a color map from a list. So you can reverse any color map by doing

colormap_r = ListedColormap(colormap.colors[::-1])
