The issue is obvious in these images: http://i.imgur.com/0sixStb.jpg http://i.imgur.com/12eQb4y.jpg Of course, they were not rendered with darktable - that's why I asked OP to re-create the scene as CR2, or get the originals from the reddit poster. Adding random noise to the cleaner image will not give magenta shadows. However, the random noise present in the raw image will result in magenta shadows (or other color casts, depending on WB).
