new python-colormath breaks colorific

[mfeif]

They're doing some pretty major overhauls to python-colormath...

Thanks for letting us know. Did it give you a stacktrace?

[mfeif]

Yep:

>>> from PIL import Image

>>> from colorific import extract_colors

>>> palette = extract_colors(Image.open('/Users/mjf/Desktop/download.png')) 
---------------------------------------------------------------------------

I pinned colorific to a known good version of colormath, and made a new 0.2.2 release. Please reopen this if you still run into this problem.
