I came across a few cases of green/magenta noise in shadows when reprocessing some NEX-5N photos. It isn't only Foveon sensors.

Probably limited dynamic range is the real problem.

Same with my Sony A7S. And a pal is a pro photographer with some serious Canon kit and I noticed some of his pics he posted on Facebook had green/magenta in the shadows. Best not try to increase the exposure of the shadows and let them be, umm, shadows.

Or go over the shadows in Photoshop (or similar) with a big soft brush in saturation mode. Or in color mode. Set a low percentage so you can build up gradually.
