Note that I'm not claiming that there is a problem - and I do not know
much about copyright law.

I was just a bit surprised when I saw that license, since the license
for Inferno, Plasma and Viridis seems to be CC0 (i.e. no copyright).

https://github.com/BIDS/colormap
http://creativecommons.org/publicdomain/zero/1.0

Inferno and Plasma was made by Stefan van der Walt and Nathaniel Smith,
while Viridis was made by Eric Firing and then modified by Stefan van
der Walt and Nathaniel Smith.

I recommend that you try to find the original author of each of the
other color maps and then try to find out if they specified any
licenses for their code. - Yes; that is probably a lot of work with
that many color maps.

Here's a Wikipedia page that might be useful for you, especially the
section about compatibility, if you are going to use licenses that are
different that the ones the original authors specified:
