This is fixed in the GitHub version in commit #47 , but not yet uploaded to PyPI.
As a workaround, install viscm with

pip install git+https://github.com/matplotlib/viscm.git

until the maintainers upload a version to PyPI.

I just tagged 0.9 and publish to pypi. Closing this issue, please report if it is not fixed.

Works fine, thanks!
