viridis

“viridis” is matplotlib’s new default colormap from version 2.0 onwards and is based on a design by Eric Firing (@efiring, see http://thread.gmane.org/gmane.comp.python.matplotlib.devel/13522/focus=13542).

viridis_white

“viridis_white” is a modified version of “viridis” that goes to white instead of yellow in the end. Although it remains perceptually uniform, the light colors are a bit more difficult to distinguish than yellow in the original viridis. It is useful for printing because one end of the colorbar can merge with a white background (by M Meschede).
