python-colormath currently requires Python 2.7 or Python 3.3+. There are no plans to add support for earlier versions of Python 2 or 3. The only other requirement is NumPy.
For those on Linux/Unix Mac OS, the easiest route will be pip or easy_install:
pip install colormath
If you are on Windows, you’ll need to visit NumPy, download their binary distribution, then install colormath.
