What version of darktable are you using?  This has been an area of active 
development in the current dev version (1.3),
although it's not finished and hanatos, who has been working on it, is now away 
on holiday so it won't be worked on any
further in the next few weeks.

I see you're using a 6D.  I was seeing the same magenta issues as you with my 
5d3, so it might be similar.  Take a look
at the bug report that I posted on the rawspeed bug tracker:

http://bugzilla.rawstudio.org/show_bug.cgi?id=607

Basically some of the whitepoint values in the rawspeed config file (that 
darktable uses) were wrong.

Something that might be a workaround in the short term is to use the Adobe DNG 
converter to convert your CR2 to DNG and
then develop that in darktable.  If you don't see the same magenta problems in 
the DNG then that would be strong
evidence that the rawspeed whitepoint is indeed the culprit.

Cheers,

Rob
