Shameless plug for python-colormath, which has been cooking since about 2008: http://python-colormath.readthedocs.org/ http://python-colormath.readthedocs.org/ Has a lot of the same conversions/comparisons/color spaces, excellent test coverage, and in my own biased opinion, pretty good documentation.
