"Fixing" G-Log Ultimate Footage

Recently I shot several days worth of material with a shiny new FS100, and a few other cameras. I was (hastily) trying out the G-Log ultimate profile thinking (incorrectly) that any significant color shifts could be brought back to the other profiles (all others set to generic 'neutral' profiles) in post. I'm finding it's not that easy (should have known). Though, yes, the footage is amazing from the FS100, the G-Log Ultimate colors are too far off from the real world colors (at least regarding reds). And, since cars are the subject here, it's no good to have a maroon car appear orange in 75% of the final edit.

Since the shoot I have figured out that a corrective issue for this in camera was to simply shift the "color phase" back to 0 (or closer thereto). Frank Glencairn's profile has it at -7, which is shifting the color wheel too far when true colors matter. (After extensive testing... which I should have done earlier, I have complete several shoots since, and this color setup is working great. But, back to the orange car...)

How can I achieve the the same color corrective result of "shifting phase" in a program like Final Cut Pro X? Or, do I need to do it in DaVinci Resolve (current version crashes constantly on my system for some reason, so this isn't as easy as it sounds.) My understanding is that "color phase" moves the entire color wheel. I've spent a fair amount of time searching online and messing with different approaches, but haven't been able to find anything that brings the orange car back to it's native maroon. (and, for what it's worth, the FIA curbing that is supposed to be red is also orange. Aesthetically, very nice, but not correct.)

Thanks,

Ryan

....and it dawns on me right after posting. Sometimes the answer is easy, and I was trying to make it too complicated. Just needed a hue adjustment using the hue/saturation filter. (bangs head on keyboard.)

Re: "Fixing" G-Log Ultimate Footage

Hi,
Is it possible to post some framegrabs or post a small MTS file. Perhaps then we can help.
I've also shot with this profile. But for me it was not needed to go back to the 'real' colours.
