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 illuminants. * Chromatic adaptations may be _slightly_ more accurate (we're talking miniscule) on certain hardware.
