Hello, I often find that a lot of time in my raw editing is spent trying to tame wild wild out of gammut colors, and that a lot of the tools in Rawtherapee that can do so either have side effects or seem to occur after tone curves in the pipeline, even the gamma referred rgb mixer, which creates artifacts of various kinds, such as color inversions and flattened out or pre-clipped regions. Also sometimes the negative values created from out of gammut dark colors tend to create issues. What I would like to know how to do is find the numeric values in the color matrix inside a dcp file so I can left multiply it with a desaturating matrix, and use that new color matrix whilst still in linear color space for a better starting point, even if it means that the other tools inside the DCP aren’t applicable anymore, such as the LUT.
To enrich discussion, I also created this nightmare gamut scenerio of a play_raw. Deliberately difficult gamut colors in macro shot of hex nut
