Implement a powerfull coulour matching
When I am doing extensive image editing, especially for compositions. I am frustrated by the tools provided by Gimp and the empirical way to try to get a good colour matching. Actually, you need to have a 6th sense to play with many operations like temperature/colour balance/chroma/hue/lighting/saturation/exposure/Gamma...
I would like to have a scientific approach to get a colour mapping and a way to save it for further use.
Actually, G'MIC provides some interesting tools to perform this task. I think such tool is mandatory in a software like Gimp.
