Have a look at how cmocean (https://github.com/matplotlib/cmocean) works under the hood.
I think the options are: - use a module to supply your color maps (from my_cmap_collection import my_cmap) and then pass those objects through to the functions - have your module call the register code on import (or on calling a helper function which call the registration code) so that you can simply pass the string name through and `get_cmap` will do the right thing.
