register_cmaps(*args, user=None, local=None, default=False)

Register named colormaps. This is called on import.

• user (bool, optional) – Whether to reload colormaps from user_folder. Default is False if positional arguments were passed and True otherwise.

• local (bool, optional) – Whether to reload colormaps from local_folders. Default is False if positional arguments were passed and True otherwise.

• default (bool, default: False) – Whether to reload the default colormaps packaged with ultraplot. Default is always False.
