python-colormath 1.0.2 has been released, which addresses an issue with
chromatic adaptations.

What is python-colormath?
python-colormath is a developer-oriented module that abstracts a number of
color math operations behind a small set of classes representing color
spaces (IE: RGB, CIE Lab, XYZ, and LCH, etc.). Color conversions, delta E
comparisons, and density calculations are all relatively involved, but are
hid behind the simple API. For example, conversions from RGB to CMY and CMYK
are trivial, while conversions from Spectral to LCHab are equally so (even
though much more math happens behind the scenes).

What's new in 1.0.2?
* Conversions between all known illuminants is now possible with several
different chromatic adaptation transforms (Von Kries, Bradford, and XYZ
Scaling). Previously this was only possible for some well-known CIE
* Chromatic adaptations may be _slightly_ more accurate (we're talking
miniscule) on certain hardware.
