If you're not sure how to proceed, I suggest making multiple captures and taking careful records. Work from the controls' default settings. Vary each control to create all possible control-step combinations for tint and color. Take your sample and make an RGB-sep analysis (like mine) for each one.

Thanks for doing this research, but I have nothing like "color" and "tint" capture-side which is why I decided to capture flat. I do have a preamp with "chroma gain" and "luma gain", but it's even harder to dial-in with them. Hell, I'm capturing in 10-bit, so I might as well make use of the extra headroom and save this headache for post-production.

The first colorbars I posted are an 8-bit RGB representation of exactly what comes out of my capture chain when capturing flat.

I think I may need a better eyedropper application.
