I have always been annoyed by the skin tones coming out of the GH3 and now the G6.
Last week I made a discovery, while trying a cheap but fun app called camerabag (photo editing software) with various stills from video shot with GH3 I found out that the skin issue could be resolved by adjusting the red hue brightness. This adjustment also made the reds from GH3 look more natural and life like. (light reds are no more pinkish, oranges and no more yellow) I then tried to replicate the adjustment in FCPX, motion, after effect, speed grade, resolve... and it was just not possible. Weird.
Yesterday I found a way of creating a .cube file's LUT from the settings of camerabag and the results are amazing. With this LUT applied the red color of GH3 and G6 video looks a lot like 5D markIII and Blackmagic cameras.
Here is the LUT applied on a graded still from video of G6
