The colour issue isn't really an issue. Skin tones remain great pretty much no matter what. Mark 2 is just more neutral than the Mark 1.You can use a custom MKii profile from AbelCine (here)or Shane Hurlbut for warmer looks. The sensor can produce classic Canon colour no problem with some minor matrix adjustments.
After more tests with sharpness, I suppose some people may have issues even with it turned down. The MKII really is a 4K cam trying to burst out of a HD cam's body (Canon really should have allowed it to record 4K externally). Diffusion filters are, of course, an easy fix.

I hope "blue tint" is very easily to fix in camera . I know , in post I can do it later , but from my experience when you have 8 bit camera it is much better to get right colour look in camera . Next week I am going buy mk2 but I have to be sure that I will easily match mk2 to mk1 , no in other way . mk1 looks much better for me . I shoot a lots of video with people , skin tone is priority . Unfortunately I am getting mk2 from second hand , I will be not able to test it and send it back if I do not like it .
I do not know how to get profile from Shane Hurlbut website .
