Just for the record, after long time I have returned to this issue of green
(mostly) color casts of E-M5 raw files in darktable. I purchased the
Huelight profiles for E-M5 and also copied the profiles from RawTherapee.
After conversion with dcp2icc and import into darktable, both of these
profiles seem to give improved results regarding this green tint.
After some testing it seems to me that all my issues discussed here are
resolved by using RawTherapee dcp/icc profile.
Hope this helps,
Stepan
