What names can be used in plt.cm.get_cmap?

Matplotlib provides a number of colormaps, and others can be added using :func:'~matplotlib.cm.register_cmap'. This function documents the built-in colormaps, and will also return a list of all registered colormaps, if called.

Example

from matplotlib import pyplot as plt

cmaps = plt.colormaps()

print("Possible color maps are: ")

for item in cmaps:
   print(item)

Output

Accent
Accent_r
Blues

viridis_r
winter
winter_r
