Confirmed; I get the same result.

I can replicate it too. I believe it's due to upstream changes in colormath, issue https://github.com/99designs/colorific/issues/17

I just put out a new release 0.2.2 where we pin colormath to a known good version. Using this version fixes the problem for me. Please give it a try, and reopen this issue if you have any problems.

Hi Martin,

How have you installed colorific? If you install it with pip, it should actually uninstall colormath 2.0.2 and install 1.0.9 in its place.

Alternatively, try installing it into a virtualenv sandbox and see if gets the right version of colormath there.

virtualenv env env/bin/pip install colorific

Hope that helps!

Hello Lars,

I quickly realized colormath was installed as 2.0.2 and pip install -U -r requirements.txt didn't remove it.

Once colormath was re-installed everything worked fine.

Thanks for this awesome little library!

No worries, glad you're enjoying it. Happy coding!
