I wonder if this is not like including in the photo a Macbeth Chart [1] and then trying to color match your image so that the swatches on the Macbeth Chart look the same digitally as well as in real life.

One bottleneck of course is that the display you are on, where you are viewing the image, is likely not to have a gamut rich enough to even display all the colors of the Macbeth chart. No amount of fiddling with knobs will get you a green as rich as reality if there is an intense green outside the display's capabilities.

But of course you can try to get close.

(I seem to recall, BTW, that these Greytag-Macbeth color charts are so consistent because they are representing each color chemically. I mean, I suppose all dyes are chemical, but I understood that there was little to no mixing of pigments to get the Macbeth colors. I could be wrong about that though. My first thought when I heard it was of sulfur: for example, how pure sulfur, in one of its states, must be the same color every time. Make a sulfur swatch and you should be able to constantly reproduce it.)
