The viridis_white colormap is a modification of the Viridis colormap that was introduced in Matplotlib in 2015. In viridis_white, the yellowish sequence is replaced by a white sequence. It allows some additional flexibility when it comes to using a colormap on a white background.
The viridis_white colormap is based on the following Python implementation: https://docs.obspy.org/packages/autogen/obspy.imaging.cm.html
The present submission contains
- viridis_white.m: the function that creates the viridis_white colormap
- viridis.m: the viridis colormap in Matlab for comparison purpose 
- Documentation.mlx: A Matlab LiveScript that illustrates how th viridis_white colormap looks like can be used
Any comment, question or suggestion is welcome
