I see that a number of color palettes were added to chimera a little more than a year ago now:

I would like to try using viridis (https://bids.github.io/colormap/) instead of standard rainbow/spectrum for coloring a protein from its N to C termini. Would someone be able to give me direction on how to create a new a color palette to do this? 

The RGB values making up viridis can directly be found here: here: https://github.com/BIDS/colormap/blob/master/colormaps.py 

Thanks,
