Description: PR Summary Right now we are deprecating access to the global colormaps, but users can only avoid it by doing newcmap = copy.copy(cmap) which is a bit heavy-handed. Here we provide a simple copy method to Colormap so we can do newcmap = cmap.copy(). See discussion in #19609, #16991, #18503 PR Checklist Has pytest style unit tests (and pytest passes). Is Flake 8 compliant (run flake8 on changed files to check). New features are documented, with examples if plot related. Documentation is sphinx and numpydoc compliant (the docs should build without error). Conforms to Matplotlib style conventions (install flake8-docstrings and run flake8 --docstring-convention=all). New features have an entry in doc/users/next_whats_new/ (follow instructions in README.rst there). API changes documented in doc/api/next_api_changes/ (follow instructions in README.rst there).
